Yes I'm still using my egr with offroad H pipe and no smog pump. I was thinking of aerodynamics.. maybe play around with a custom plastic "skid plate" for now that covers from bumper to tranny..that would be cheap. Never thought of my alignment I do have caster camber and adjustable control arms. I'm fully synthetic except for tranny..gotta do that. I wanna order a tune, there is so many out there, but I want to be sure I'm keeping my stock throttle body and MAF before I do that..
