Thanks Marc....I plan on a dyno tune at some point, but appears I need to sort the trans issue first. I drove my 92 today, amazing difference in shifting vs the 90.....also my the 92 ZR-1 seems slow in comparison(and the 92 runs 12.42 @ 117.5) Whatever the trans issue is it is certainly hurting the cars speed on the track. Might have to wait until next year to sort, I have the Callaway TT on the lift right now....may need a new trans or a rebuild as it does have 140K miles on it.
