Congratulations, awesome man! I would suggest to take the tuning slow with that turbo. Do the vacuum areas first (don't go into boost). And pull out a good amount of timing to start with when in boost. If you had a set of chassis ears you could listen for detonation when you start increasing the timing...
You're idle vacuum (-5 psi) is a lot lower than mine (-9 psi). What does the MAP sensor read when the engine is off? What does it read with light throttle as you rev it up?
