Well does the 2.5" manifold count as an upgrade? Or would I need to fabricate some crazy header concoction for the turbo setup?
I understand that each part relies on each other but it seems like it would increase a LITTLE bit... I mean I remember reading some results from somewhere on here and it said the offy and 390 would give an extra 15hp so it seems like I would feel that.
But I do know that it is rich so how would I adjust that? Just get a kit and try and try and try? Or do you guys have a suggestion for a jet size?
