What did they tune your AFR to? And cat's replaced with test pipes yields about the most gains.
I know everyone can't run them; also Dyno numbers in 4th gear on an A/T will definitely read lower than 1:1 5th,,, the M/T cars have 1.27:1 4th gear to a 1.41ratio 4th in the A/T...so not as much loss on the M/T's.
Only thing is,some tuners won't tune 5th because of the 170+mph speeds.
