Default We put our cars on the rollers today, but WTF is wrong with my moms car?
so me, my mom and brother got our cars on a dyno today, i noticed something wrong with my moms print out and she is about 10HP/20TQ short from me and my brother, all cars are LS3/M6 cars

videos for all 3 dynos will follow as soon as i can edit them

my car made 374RWHP/373RWTQ (Only mod is GMPP Axle Back Exhaust)





My brothers made 372RWHP/372RWTQ(100% stock)





My moms car made 363RWHP/355RWTQ(only mod is GMPP axle back exhaust)







now can some one tell me why my moms HP and TQ curve got all fucked up after 110MPH and wasnt smooth the whole way through?

I think my moms factory tune is messed up

That's what it looks like. Did they end up putting a tune on it?

No we only put premium fuel in our Camaros


I don't know if they used an obd2 scanner or not, I know after the pulls my moms and brothers cars were throwing codes after we were all done

did they turn off Traction controll for your moms pull? either they tried to pull timing.. or TCS kicked in.

Good taste in cars there. Have you raced the cars against each other yet?

Her car is getting some knock retard. Its completely normal for a car with the stock tune. Talk to Speedtek about getting them dyno tuned and the problem will go away plus you will pick up a few hp.

My cousin had a great experience with SNL with his cam install in his 06 GTO, so I figure I would give them a try
