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

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, or something fishy went on with her dyno

Probably an issue with the way the car was strapped down and may have moved some causing the strange graph. Watching the videos every car moves. They did a crappy job strapping the cars down which accounts for the discrepancies.

Properly strapped down car on a dyno looks like:

BTW - the numbers posted are STD which will always read higher than SAE. I would say you are around ~368WHP/TQ with SAE readings which is in-line with what I put down in my 2010 SS.

I laid down 430WHP/377WTQ SAE in my 2011 GT Friday before last.
