You might be pushing 18psi on the stage two tune, but the thing about turbo's is it's not just about psi it's about air density and we all know cooler air is denser. That's why with all things equal an upgraded turbo can make equal power @ say 12psi to a stock turbo @ 16psi.
FMIC is more important than midpipe and axleback section combined.
FMIC + Catless DPs > Catless DPs + Catless Midpipes + Axleback/Muffler.
Anyone beg to differ?
