I'm about to buy a 99 cummins with 75k miles as a work truck. Looking to get some good power numbers out of it but am hoping to stay away from internal engine mod and tranny rebuilds, yet I wanna do more than just a chip, intake and exhaust. Any suggestions on what products to get? Truck will also be running 35" tires

 

First off built tranny that is going to have to happen. Next it really depends on how much money u wanna spin. and if u are wanting to keep it electonic or p pumping it. If it were my truck i would run a redline, Edge comp drag, and a smarty. Run some mach 7 or 8 injectiors and run nothing more then a 64mm turbo u will have to get a lift pump of some sort i like the raptor myself. That combo i just gave your should put you around the 500 to 550 mark and be very dependable.
