Shift at 8800 you want to get that fallback on the shift to be 80-8100 or a tad more. Some of that will be found in power numbers and tuning but IMO its still pretty tight.

FWIW we run a billet 7" in the Vette. Shift 1-2 is earlier than 2-3. 1-2 is typically 95-9700 and 2-3 is usually 97-9900 with the "old combo". We typically see a 500 rpm drop on 1-2 and a 700 on 2-3. Still not perfectly happy with it and have now gone to a lockup deal. This is with a ProFlite behind the SB.

FWIW never seen any issues with the thrust on a 7 converter. We have run one in the red car for a few years, and I have run one for a few years before that with the 99.

Here is a pic of a racepack log from an 1/8 mile pass of 5.10 just for comparison sake. Clearly the tuneup was off a bit on this pass as well. 60- was only 1.15
