    Might I suggest using software like Blucats to remap the transmission instead. Never was a fan of the TBI (or even Vortec) shift points at part-throttle.

    They do run pretty good. What are you using for ignition and engine management on that project? Years ago I figured out how to run mine on a 7427 using the stock 3.4 camaro DIS.

    In my experience 30-50 IAC counts will help fix the split BLM value at idle on a LT1. At Zero counts that split can get fairly wide.

    On the otherhand a TBI likes low IAC counts. 5-10 steps on...
