Just installed the diablo predator on my 2004 2500hd and after i load the diablo program (dont remember what its exaclty called not infront of me ) into my truck on the little screen underneath the gear selector where it tells you the mileage it says decreased engine power i dont under stand why .. i also dont notice much of a power increase either not trying to gripe on there product by no means, just something doesnt seem right i dont know if its the truck or just something else thats faulty.
