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
