Hey man, quick question that I think you would know going by your sig on swedespeed. I'm getting a hand me down 2002 volvo s40 next month. The 420cc injectors you had on stock tune, did you have to modify anything for the added fuel?  And is there any advantage running a phase 2 maf on phase one? You mentioned VVT tricks and curious what you did also. Any help would be greatly appreciated.
