stock 05 wrx w/:
aftermarket up/down pipes
large fmic
baseline vs. quick tune
for those that think i just turned up the boost...wrong. couldn't get the boost to stabilize and hold past 5k. it kept falling to 7ish psi @ redline no matter what i did w/ the internal boost feature.
20whp 15wtq gain from just basic tuning. if i could get the boost to stabilize we could've seen gains of 30whp+. much smoother power than stock as well.
