91 Tune.

Can someone tell me if the 91 tune automatically increases tranny shifts to firm? And also what hp can I expect on my 02 Camaro Ss Ls1 auto from this 91 tune.

Yes, on the LS1 F body cars the tunes firm up the shifts by default.

Hi Mike, but what kind of hp? Can I expect on Ls1 car...from 91 tune......
