[Cummins Corvette]

I was talking with Rich Gellett, the owner of Gillett diesel in Bluffdale Utah today. He said that if I got some 300hp injectors and had the pump taken off and got the pump rack travel increased from ~12mm to 21mm by his shop that the 5.9B motor was capable of pushing enough fuel to make AT LEAST 500hp. This mod has pegged a 1800 degree pyro (pre-trubo) and distroyed a few motors in his shop. How come I have never heard of this mod on this forum? Has anyone had this done?
