    This is my first turbo experience and just working out a few gremlins. 9.5:1 vortec SBC blowthrough set at 26* total with 10lbs of boost, and w/m (375 ml) coming in at 5lbs. Afr's are decent but a little rich at WOT (mid 10's). My question is should I leave well enough alone, add some timing, or reduce the rear jets from 84 to 82. I want be conservative and make sure I don't blow this thing up, but not sure what is my next logical move, or if this is where I should stay with the tune. It is driven on the street only. Any advice/comments appreciated.

    Is this a vortec supercharger or a vortec engine with a turbo? If turbo what are the specs?

    sorry. It is a turbo on an l31 vortec sbc. It is an Ebay t70 turbo with a .84 a/r on the hot side and .70 a/r on the cold side.
