U7191 Question for a 2006 chevy impala ss?

[KyleG]

Hi, i just bought a Diablosport Predator flash tuner-U7191-for my 2006 Chevrolet Impala SS. I mainly bought it to bypass the factory rev limiter at 3500 RPM's (in park or neutral only) so i can rev it to here my pipes when i am not moving. Now, it says that i am able to change rev limiters in the Predator manual, but when tuning it, it says that i can only change the over rev when driving, and that is not what i bought for. I mean it is nice for a little more power, but i mainly bought it so i can rev the engine past the factory 3500 rev limit when parked. Is there anyway of doing this? Or is there a download i can do to bypass this? I'd greatly appriciate the help on this one, Thanks-Kyle.
