Thanks guys, faster times to come. Heck I improved it from 8.6 sec to 8.3 sec from yesterday to today.

I'm on full manual control right now, since I'm trying to figure out why the performance increase from the nitrous activation is so weak compared to the coupe's times. Right now it doesn't even make much difference whether I run on 91 oct/meth or 95 oct/meth. Once I get it all figure out, I will be using the JB4 nitrous controller function again.

One thing I can tell you is that I have been experimenting with CPS offset, and it almost alway results in slower times, and often uglier timing results overall. All these runs are with no CPS offset. I have literally ran hundreds of 0-130 runs without CPS. I think 99.9% of the guys out there running much milder setups out there have nothing to worry about the DME having complete control of timing.

Also, my 7.7 sec 0-100 is in some pretty good company:
