kinda changes the rules of tuning. You can flow all that extra air at a cooler temp and therefore crank your timing up a little more for more power. No way stock turbos will run 19psi at 19 degrees of timing, the intake charge is way too hot and it will detonate.
I wouldn't be suprised if you could go up to 21 degrees. :) PRobably should, you'd probably also make more power. :)
: of timing at WOT on the dyno. My tuner friend felt it was little conservative .
