A juicy girl got me, again
This was mine when I first swapped more than 7 years ago. L31 with a factory GM LT4 cam, 1.6 rockers, shorty headers and the TB lip removed. If I remember for my startup tune all I did was remove the VATS, set the Park/Neutral switch to None, bumped up the High octane spark map and idle spark map about 4°. Was running stock VE and MAF tables at the time. Ran so smoothly even after a cold start.

When I first started tuning WOT. Still had 100% of the torque management in the tuning and ran 0-60 in about 9 seconds. 3 ton van with 3.42 gears.

I had to bump up the base idle airflow by 30% and base idle spark to 28 degrees to get mine to idle good. She does great now. HT383 cam with 1.6 rockers
