Nope, thats my limiter! (thats actually my car reving to 7200rpm in 4th gear on both dyno runs). Dont ask me why, but its got short ass gearing. Maybe it has shorter diff gears then the standard 4.11s, or the actual gearbox has different gearing (I think it might have some straight cut gears, whines like a bitch)
Either way, thats all the way to limiter (7200rpm) in 4th on both runs. Something aint stock
Unknown dump, RSR 3.5 front and 3.5 from the cat back from memory. Still running a cat too, but its getting on now and is cracked and shitty. Still, pulling ok figures i guess
