Its very hard to believe that you have all that stuff on the car and have zero idea how to go about base tuning. Where did you buy your vpc from how long ago and how much was it?

as far as tuning here is a shot in the dark for your starting point's

response 6 o clock

gain 12 o clock

idle 7 o clock

base fuel pressure 38 PSI

-25 across the board HI and LO table

start at 15 psi and makes a few logging runs. make fuel adjustments based on knock and timing. slowly increase boost knock should be under 5 counts timing should be atleast 16-17*

i had the car with 3 in exhaust and an intake then i broke a rod. i took the motor out with intentions of putting it back together stock and i guess i got a little carried away. I paid $550 for the vpc, from my buddy eric.
