I dig your style but it doesnt surprise me considering i"m from the northern part of the great Big Sky Country. Anyways, I'm living near Asheville , NC rebuilding a dam at the moment and i ride a 05 STi with some mods. Currently installed is a deadbolt 18g sucking 18 psi or .13Mpa. With and Perrin front mount and 4" down pipe into 3" out towards the back with stock end section finishing. I'm considering upgrading to a something like a 20g and increasing her boost around 19-21psi on 93 octange. So i was wondering if you had any advice on this swap or ideas?
