Accell used to offer a lingenfelter designed software setup I think it was the CALMAP thingy, You could plug a laptop into a GM harness and adjust all kinds of things. Spark curve, fuel map timing, etc...
do an inrternet seach for calmap software, I remember the kit was kinda expensive, and in the wrong hands could do a ton of damage to the motor.
