4-5 Shift?
I was at the track last weekend with the car and I have a 3200 FTI converter. On the 4-5 shift, it sounds like the rmps are all over the place right before the traps. I've heard others have had issues with a 4-5 shift with aftermarket converters. Is this true? Going to get a log the next time I'm out to send to my tuner.

Have you tuned the TCM? Adjustments in line pressure can be done based on TCC slippage vs commanded. The pressure gets ramped up harder the more slippage from commanded occurs.

Yes, I've had the TCM tuned. car launches great and every shift after is great. It's the 4-5 the converter feels all over the place.

I’m assuming your tuner will want you to datalog it and send it to him. Feel free to post it up here too and we can check it out.
