As far as IH is concerned the ficm program that came with vxcf5 is the bad one, vxcf7 is alot better(it should slowly ramp up the injectors when you first turn the key on. A kind of( click...click...click..click click click CLICK CLICK kind of sound.  Thats the best I can describe the Buzzing sound of the injectors.
