This winter I',m pulling my 525 efi's and freshing them up. Bearing, rings, top end the whole 9 yards. My question is I want to do some mild bowl porting and runner clean up. Along with this will Port match intake runners and clean everything up that Mercury did not due. By increaseing the air flow with the head work will the computer still be compatable and the injectors be able to keep up with the increased flow? Cam, Compression are going to stay Stock.
