I would add to this thread, everyone should check the adjustment of the throttle blades....they should be open from .0025-.003" with a feeler guage checked between the blade and the bore, this will give a nice idle of aprox 1700ish with turbo installed. From what I have measured myself some butterflies are factory set way over this range, .007+ this while not a issue with stock induction will give idle of 2000+ with the turbo install.

Just a fyi.:typing:

So if they are out of adjustment do we have to then adjust the tps to get .947 again or as long as the baseline is good just adjust the blades?
