I have a follow-up question too.

1. What do increased line pressures do ? (i thinking more hold force against slippage under high HP conditions)
2. What are the optimum and/or safe line pressures we should be using?
3. I did the transgo shift kit in my tranny but didn't install the new pump valve and spring because I didn't want to take tranny out... can I tune to duplicate what that pump pressure spring does? If and when I do a TC upgrade.
4. Which settings control how hard and which control how fast the trans shifts?
