Ed,
When you take off from a dead stop and the vehicle doesn't take off right away that is the T/M and when it shifts and the vehicle does the same thing that is also T/M. The stock programming takes out 15-22 deg og timing neg. That GM's way of trying to save drivetrains. Instead it is a pain.
On superchargers, most have been set up for stock motors. Like the Whipple they run about 5 1/2lbs of boost to bring the HP from 316 stock toto about 435. You do have to run prem fuel but it does burn better and keeps eveything cleaner. This making the vehicle perform better and helping with increasing your fuel milage, even if not supercharged. When you use a twin screw supercharger like the Whipple you are going to get the power down low and you will use less throttle to do the same job you are doing now. This helping you increase your fuel milage and also getting the T/M out will help you to.
