Get it running as a foot brake set up and then go back to the 2 step.

First I deactivated it in the ecu, then I removed the wiring from it.
I'm trying to get it back to running right without the 2 step. I ran fine before. I had it idling at 1000 rpms, drop it in gear and hold 900 rpms. When that comes back. Then I'll tackle the 2 step.

BTW you stated that this all seemed to start after using the launch funtion in the ECU, in what manner does your system limit RPM? does it do Ign. only, fuel only or a combination of these?

The launch control function can cut spark, fuel or timing. I was told for the N/A just to use the spark. It worked flawlessly in neutral but went ballistic when against the converter.
