Bentune Performance

another "just needs a tune" has turned into a process of discovery, diagnosis, and now repair. this 2021 Silverado was experiencing some transmission-related issues that, after some testing & tuning, was determined to be maybe a faulty solenoid or possibly some kind of assembly error that required a teardown and inspection. upon doing so, a burned clutch was found, indicating our suspicions might be correct. it will need to reassembled with new parts so that all the clearances can be verified, but we are thinking it just wasn't put together with the correct tolerance. 6, 8, & 10 speed transmissions are known to have several issues, it's just unfortunate that this one appears to be bad right out of the box. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #ltx #L86 #V8 #supercharged #supercharger #boost #boosted #mechanic #mechanicsoftiktok #racetruck #Tuesday #work #LFG

just another crusty, rusty, junky old farm truck on the dyno today. it's been around the block a time or two and seen better days. I tuned this truck a couple years ago with a "milder" engine in it but the owner decided it was time for an upgrade because the old engine just wouldn't stop. I guess it was getting boring. the new setup is bigger & badder. too much, in fact, for the headers that are currently on it, I believe. so he'll have to have a custom set built to take full advantage of the engine's potential. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #monster #tractorpull #hook #pro #rusty #junk #mechanic #mechanicsoftiktok #racetruck

"just needs a tune" turned into "can you figure out what's wrong?" which turned into "WTF is doing on?" if you missed the last video, this truck was just dropped off for tuning and after observing a rough running condition, I determined it had no compression and cylinder #3 . I wanted to just send it home, but the owner asked if I could figure out exactly what the problem was. naturally, I was unable to say no. after numerous tests and measurements (spoiler alert) I still don't know exactly what the problem is, but it appears that it has some knock-off parts in it. it's probably valve springs as well as the lifters that are the issue here. no matter what the problem is, the heads need to come off and be gone through and I would take a good look at the lifters while the heads are off as well. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #inspection #diag #wtf #Friday #work #trash #ugh #fyp #fypシ

the wiring never ends 😫 I haven't given up yet, but I'm close to throwing in the towel because I have work piling up like crazy. this truck was supposed to be in and out in a day or two and it's been on my dyno all week without even being strapped down yet 🫤 #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #OBS #lsswap #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racetruck #wiring #repair #diagnosis #work #Friday #LFG #thermal #camera

perfectionist, maybe. perfect, definitely not. I made the fatal error of assuming this truck had a certain component in it when it actually had a different one. here in this video I demonstrate what the actual issue was, what the effect was, and how to correct it. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #btr #BrianTooleyRacing #DIY #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #Friday #work #ifixedit #next

After doing a startup calibration for this truck, it would not run for the owner when he tried to fire it up for the first time. after he dropped it off for me to go over, I figured it the problem. there are many good injector adapters on the market, but there are just as many that are not made correctly. some have damaged wires, some (like these) have loose pins that won't seat correctly, and I've even seen some missing pins altogether. my go-to solution is to eliminate the adapters altogether whenever possible. crimping on new connectors to the factory wiring is pretty much fool-proof and guarantees no surprises. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #btr #BrianTooleyRacing #truck #cam #DIY #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #work

I had this Camaro dropped off for tuning after the owner was dissatisfied with the work done by another tuner. when I got started working on the car, I could not get it to run. this is abnormal for me for a car like this as they're usually pretty simple to get going on a base calibration. after the series of questions with the owner, there was some confusion that arose regarding the fuel injectors that led to me determining that I could not tune the car in its current state. after that decision was made, I got a little curious and decided to pull the fuel rail off and inspect the injectors a little bit closer because I was already in the middle of putting spark plugs in the car. A little further inspection from there led to a whole new diagnosis. now, a car that was dropped off were "just a tune" is having some minor engine work done before tuning can commence... as usual, lol. they almost never "Just need a tune." #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #Chevrolet #Chevy #Camaro #SS #6speed #automatic #lsa #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racecar #streetcar #diag #Friday #work #lfg

this C6 Z06 was dropped off for a lot of issues being resolved. The previous shop that worked on it actually damaged the TR6060 and did a very poor job tuning the car. One of the first things I encountered was a mismatched set of spark plug wires. this is often an indicator that whomever was doing the work was not very interested in turning out a quality product. this is a very easy situation to resolve and should never be overlooked because it absolutely impacts how well your engine runs. anything you can do to get all eight cylinders running the same, you should do it. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #Chevrolet #Corvette #C6 #Z06 #LS7 #LSX #streetcar #racecar #blackonblack #6speed #manual #transmission #btr #mechanic #mechanicsoftiktok #Friday #work #LFG

here's a quick funny one for you guys 😂 #Bentune #hptuners #tuning #dyno #dynotuning #GM #Chevrolet #Chevy #Silverado #lsx #Friday #work #LFG #easyone #funny #haha #justkidding #notreally

on today's episode of "Just needs a tune," we have a freshly rebuilt 5.3 with a cam and some head work. the truck exhibited a rough idle condition so I pulled the spark plugs for inspection. all 8 were fouled, of course, but I didn't notice how one stood out from the rest.... #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #DIY #howto #diagnose #hopethishelps #mechanic #mechanicsoftiktok #racetruck #work #Friday #LFG #TGIF

has a 2017 SS dropped off for tuning. it's been heavily modified with a LSA supercharger and custom camshaft along with some fuel system upgrades. right off the bat, I found several things that seemed off in the tune but felt it should be safe enough for a baseline pull. the car ended up safe, but very rich with relatively low timing, so there's power left on the table. I will be starting over from scratch as the injector data was incorrect and that means a very large error has been baked into the tune. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #Chevrolet #Chevy #SS #ZL1 #CTSV #LS3 #LSA #supercharged #boosted #alltheboost #6speed #manual #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racecar #streetcar #Monday #work #LFG

after wrapping things up on gasoline, I added some ethanol to the tank to see what this SS can do. as it turns out, it can do a lot more than what I want it to do with those stock pistons 😂 #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #Chevrolet #Chevy #SS #supercharged #boosted #alltheboost #e85 #ethanol #fuel #6speed #lsa #lsx #CTSV #ZL1 #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racecar #streetcar #Friday #work #LFG

hate to see it, but it's a very common occurrence to get a vehicle in my shop that has had very poor work done to it. there are way too many "pm me" bros in various groups and too many hacks out there taking advantage of people. nothing done to this truck's tune was correct. even if they had attempted to do further tuning other than just adding some idle airflow, it would be wrong because the injector data was incorrect. injector calibration data is the foundation of the entire tune and cannot be fudged or left untouched. it's absurd to not at least put the correct data in the tune, even if you're going to screw someone over. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #C10 #Silverado #pickup #truck #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racetruck #rework #Tuesday #work #LFG #LSswap #fic #fuel #injector #data

there's a few issues that need to be sorted out on this OBS truck, but the most pressing issue was the factory fuel pump wiring needed to be upgraded. we have an aftermarket fuel pump, in nearly all cases you will need to upgrade the wiring to something that's a little heavier duty, and possibly upgrade the relay as well. in nearly all cases, LS swaps are going to require some kind of fuel pump larger than what the vehicle currently has in it. these larger aftermarket pumps draw a lot more amperage than the old factory pump, so the wiring must be upgraded along with the new pump so things don't get a little too spicy and melt down.. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #rcsb #OBS #lsx #btr #BrianTooleyRacing #lsswap #hotrod #mechanic #mechanicsoftiktok #racetruck #wiring #work

cheap parts continue to cause issues on this cammed 2002 Sierra. I finally got everything lined out after replacing the TPS sensor, TPS wiring, IAC, and map sensor. unfortunately, after this video was made, I attempted to complete the tuning process and the transmission ended up having some issues, so tuning was aborted. I may or may not finish the truck at a later date, it had to be sent home for repairs basically as it sits in this video. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #gmc #Sierra #lsx #btr #BrianTooleyRacing #DIY #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #Monday #work #lfg

wrapped up the tuning on this C6 Z06 this afternoon. the car was dropped off running very poorly, some of which was a result of low quality spark plug wires, but mainly due to the poor tuning. after diagnosis and repairing the ignition issues, I did a few checks of the chassis, bled the clutch, and then it was just a matter of dialing in the calibration for better, smoother operation. #bentune #hptuners #mustang #dyno #tuning #dynotuning #gm #Chevrolet #Corvette #C6 #Z06 #ZO6 #LS7 #LSX #btr #briantooleyracing #cam #stage3 #streetcar #racecar #black #6speed #manual #transmission #horsepower #mechanic #mechanicsofTikTok #ignition #problems #solved #done #Wednesday #work #LFG

once again I have to send a car home that was just dropped off for tuning because of mechanical conditions nobody was aware of. this particular example illustrates the importance of verifying valve train geometry. it's a terrible idea to just buy all the parts everyone else buys and assemble it like you see so many people do on the internet. Even though it requires some specialty tools from time to time, a few quick measurements can save you a lot of heartache and money in the long run. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #Chevrolet #Chevy #Camaro #ZL1 #SS #Z28 #6speed #automatic #lsa #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racecar #streetcar #Wednesday #work #lfg

while finishing up the tuning in this 2014 SS, I decided to make video that was requested a while back regarding full throttle AFR. *MOST* of the time, a naturally aspirated LSX will be set some 12.5-12.7 AFR at full throttle, give or take. some people like to really push them to the lean side side to get every last HP out of them. that's fine if it is their car, but I generally prefer to set a car to go last a good long time vs leaving it on the ragged edge of detonation all the time. injector quality/consistency, fuel quality, and other factors will determine how safe it is or isn't to run them more to the lean side. these factors are largely out of anyone's control, so it's best to leave that 5hp on the table to keep the engine safer....in my opinion anyway. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #Chevrolet #Chevy #Camaro #SS #6speed #automatic #6L80 #ls3 #L99 #lsx #btr #BrianTooleyRacing #Trinity #intake #manifold #mechanic #mechanicsoftiktok #auto #repair #racecar #streetcar #Friday #work #LFG

After resolving the fuel pump wiring situation, my attention has now turned to the electric fan wiring. it isn't just insufficient, but an actual disaster that could also potentially result in a fire if left untouched. all of it has to go and will be replaced with some nice weatherproof relays and appropriate wiring along with a properly fused power supply. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #lsswap #btr #BrianTooleyRacing #OBS #RCSB #mechanic #mechanicsoftiktok #racetruck #Wednesday #electrical #wiring #work #lfg

Doing some out of town work this week. I'm in Las Vegas for the C10 Nationals and decided to pop in on my buddy Frank at RevSC. Frank and I may or may not be collaborating on some projects for future endeavors....stay tuned 😉 #Bentune #hptuners #dyno #tuning #dynotuning #GM #Chevrolet #hotrod #streetcar #racecar #C10 #Nationals #lasvegas #Nevada #speedway #remotework #Thursday #work #lfg
