Disconnect the battery when 1st hooking up tweecer?

If it was a contact issue as I described, it wouldn't even start....For a while I thought I was having an issue when i hit bumps, but that turned out to be mixing of versions.
Is it just stalling, mostly around idle?? You have enough mods that you may need to work on TB airflow, Neutral Idle airflow, and dashpot.....
I've saved my posts since the Tweecer site seems to go down a bit:

Ok Black Vert, I will definitely look for that. As to any changes I made? Only thing so far is turned the EGR off (just one setting change for that as I was told), delete smog, fans on sooner, delete speed limiter, IDLE 800RPM. No other changes yet. I adjusted the idle up manually just to see if it helps. Ran fine all the way home tonite.
