I just dialed in my RAF table per the guide on here and im still having some surging issues at idle. In gear it seems to be pretty happy but in park if I turn the steering wheel it will usually stall or sometimes it just goes into a fit and does it by itself. Here is my scanner and tune files. mods are as follows.
383ci LS1
Fast 90 intake and 90mm throttle body
PRC 225 heads
MS3 cam 237/242 114lsa
42lb gtp injectors
3600 stall converter
