r20 revert to r18

[07norcalsrt8]

Hello..

I have had my Diablo for about 1 month now and have never quite been happy with the shifting in r20. So today I installed r18 in to my 2007 MSRT8 and I have to say quite a difference. the shifting is alot crisper. Even in Autostick the shifts are crisper. But what I did notice is at WOT the 1-2 shift and 2-3 just as the shift happens the car falls flat on it's face for a split second then goes, it never did that with r20. Is it maybe because r20 has more fuel added at WOT?? Any recommendations that may fix the issue... Thanks

This is the exact way I installed the tune

r18
91 Performance CAI Tune
lower RPM -50 across the boad
Raised Speed limiter
Raised Rev limiter +200
Shift points untouched
Fuel untouched
spark untouched
fans untouched

Anyone???

Why do you raise the rev limiter, but not the shift points?
I'd bet the tranny shifts better with the raised shift points selected...and what about the shift firmness setting, did you change that?
