Bentune Performance

2013 CTS-V on the dyno today and, as usual, it won't be getting done as quickly as I'd hoped. the car had what appeared to be an oil leak but upon closer inspection turned out to be loose PCV lines at the catch can and the catch can drain fitting was also open, soaking the undercarriage in oil/fuel vapors. after cleaning that up, I inspected the tune and, as I suspected, it was way off. the injector data was incorrect and right off the bat, that makes everything else wrong. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #GM #Cadillac #CTSV #LSA #ZL1 #SS #supercharged #supercharger #boost #alltheboost #boosted #6speed #automatic #lsx #btr #BrianTooleyRacing #dsxtuning #kong #dsxtuning #fore #Innovations #mechanic #mechanicsoftiktok #racecar #streetcar #diagnosis

it seems like I'm seeing these issues more and more frequently. incorrect catch can and incorrect PCV line routing is causing people all sorts of issues and it is obviously getting overlooked. here's a case of a supercharged Pontiac G8 that had incorrectly routed PCV/breather lines and it caused the rear main seal to blow out, leaking oil constantly out the rear of the engine. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #Pontiac #G8 #GT #GXP #LSX #LS3 #L76 #boost #turbo #supercharged #supercharger #boosted #alltheboost #nobeltlag #racecar #repair #work #lfg #fyp #fypシ

I can't recall ever seeing a car that had heat sleeves on the spark plug wires that did not have issues directly related to them. While they definitely seem like a good idea, they are not. they actually tend to trap heat inside and cook the plug wire, eventually burning it up. #bentune #hptuners #dyno #tuning #dynotune #gm #Pontiac #firebird #transam #ws6 #formula #TA #coupe #M6 #T56 #supercharged #procharger #alltheboost #e85 #ethanol #e85🌽 #racecar #streetcar #cars #trucks #carsoftiktok #mechanic #mechanicsoftiktok #diagnosis #Thursday #work #lfg

I finally had a truck come in for a dyno tune it was actually hassle-free, so I knocked it out real quick. This 2007 classic Silverado is sporting a Truck Norris camshaft from Brian Tooley Racing along with a FTI torque converter, long tube headers, TBSS intake manifold with a LS3 throttle body and some flex fuel injectors to handle the extra airflow. This video is to demonstrate the importance of keeping your commanded AFR safe during the tuning process in the event that the actual AFR ends up being much leaner than what you are commanding. A wideband O2 sensor is a necessity for this process in most vehicles, but especially GM vehicles that only have narrowbands from the factory. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #4pointgreat #lsx #btr #BrianTooleyRacing #DIY #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #trucknorris #cam #camshaft #LFG

no good news today unfortunately for this Cadillac. after I received several DMs about where the car may have came from and the reputation, I decided to go ahead and do a compression check while I had the plugs out and basically confirmed what I had been told. I'll do my best to get the car running better than the way it was dropped off, but unfortunately I don't really feel like leaning on the car and seeing what kind of power it's putting out because that might just be what finishes it off. if I can make it idle and drive better, it will at least leave in better condition than when it was dropped off even if it's on borrowed time. I just don't want to be the one that finishes it off. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #GM #Cadillac #CTSV #LSA #ZL1 #SS #supercharged #supercharger #boost #alltheboost #boosted #6speed #automatic #lsx #btr #BrianTooleyRacing #dsxtuning #kong #mechanic #mechanicsoftiktok #racecar #streetcar #badnews #sadday #couldbeworse #Wednesday #work #Milwaukee #tools

wrapped up the tuning on a 2013 CTS-V. this car in a previous video demonstrated low compression on a few cylinders with only 2 being close to "normal." I was apprehensive to complete the tuning but the owner wanted to see what it would do, so here it is. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #cars #GM #Cadillac #CTSV #LSA #ZL1 #SS #supercharged #supercharger #boost #alltheboost #boosted #E85 #ethanol #fuel #6speed #automatic #lsx #dsxtuning #kong #tsp #Texasspeed #mechanic #mechanicsoftiktok #racecar #streetcar #Monday #work #LFG

going to do a quick thing on a 2005 Pontiac GTO today. but before I begin, I want to know if and how the vehicles calibration has been modified before coming here. The simplest way to do that is to use the compare feature in the HP tuner software. this is one of the most underutilized features by most novice and even some professional tuners. it can help you identify what has been done to the tune very quickly and allow you to target problem areas before just going into the tuning process blindly. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #GM #Pontiac #gto #T56 #manual #transmission #M6 #red #racecar #streetcar #horsepower #torque #musclecar #Tuesday #work #LFG #howto #DIY #tech #teach

not all tuning jobs result in heroic gains. sometimes, you just get a little more power, throttle response, lower fan temps, some codes go away, and better shifts if it's an automatic. this 2005 GTO had very basic mods and the result was a leaner AFR close to what I would target after tuning and timing advance that was pretty close to ideal right off the bat. tuning only corrected the slight fueling discrepancy and keep timing in it instead of allowing a couple modifiers to pull it out in the higher RPM range. if nothing else, the owner now has a solid baseline of where the car sits before doing additional mods down the road. #bentune #hptuners #dyno #tuning #dynotune #gm #Pontiac #gto #M6 #red #coupe #howitworks #Wednesday #work #lfg #explain #cars #trucks #musclecar #racecar #streetcar #ontothenextone
