I have a roush phase one package on my 16gt and was going to do a phase 2 package but being as it's currently backordered and the roush tune isn't very impressive, I was thinking about just piecing together my own and having Lund do the tune, the phase 2 uses an 80mm pulley, will a 79mm pulley and a retune require larger injectors? I was planning to just do a vmp bap, 79mm pulley the iat2 sensor vmp sells, and a Lund tune with ngk plugs, not sure what the plugs need to be gapped at either, car is an auto would that set up get me mid to upper 600's whp?
