I have a 2000 cummins 5speed with an Edge COMP 4" exhuast, and a FASS. I just put 35" tires on it and it's kinda sluggish now. I know there are unlimited things i could do but what would be the best way to get around 400-450 HP?

I dont tow very heavy this is basically my daily driver I just want it to be lil more peppy so i can beat all of the low riders in my town or at least smoke them and maybe pull at the fair.

 

needin` injectors now,skip the 275`s and call rod up at wildcat,,1.5 edms fer 550,,cant beat that

 

I was thinking of mach 2's or whatever they offer in 80-120 hp injector and a hx35 hybrid or b-1



how much power is a hx35 hybrid good for?
