We put our cars on the rollers today, but WTF is wrong with my moms car? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

UnknownWarrior · 02-26-2011, 08:39 PM

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 ****ed up after 110MPH and wasnt smooth the whole way through?

I think my moms factory tune is messed up

lower octane fuel? fuse pull needed?

Fuse Pull for sure. Looks like she is in low octane table. Talk to her and make sure she has been putting in 91 octane as the min. If so pull fuse 5 and 20 in the engine bay fuse box and let it sit for a couple of hours and then put them back in and fire the car up.

we only put premium in our cars and i did the fuse pull over a year ago to all 3 cars

The Answer Lies in the data.

Do you see the step downs in the torque curve, Moms car is pulling timing due to bad gas.

Exactly. The knock is pretty evident in the graphs of your mom's car, most likely because she fills up at crappy gas stations.

I've seen cars pick up 15whp just by going from QuikTrip to Mobil gas.

The step-downs in the tq are the result of KR's response. It could well be fuel. It could also be overly touchy knock sensors.
