maximize shift points

First off, you have a nice running car in street trim.

Second, while this is a nice conversation, and very informative for many, me included.....The bottom line is, we're talking shift points here. What that means to me is we're looking for a few "hun", and possibly up to a tenth max. You're not gonna go 11's by changing them up or down.

The numbers I posted earlier are not taking into account trans/converter slip or tire spin. Your street test proved that. I did a quick look at converter slippage at the top end (109.16, 85" circumference tire, and 6k) and it looks to be approx 8%. Obviously, the closest to zero would be optimal, but that will never happen with a auto trans/converter, especially a streetable one. At this point, i know you want to make the most of your last session of the year, so i'd try a few hundred less and a few hundred more and see how it works out.

I really think to step up significantly next year , you need to work on getting the 60's consistently in the low 1.60's and maybe work on that 109.16, meaning some power tuning.
