2001 Cummins Performance Mods
 

I've got a 2001 dodge 3500. S&B intake manifold, K&N Air filter (soon to be S&B cold air), 4" flo pro turbo back, and an edge ez, and im looking into a fleece cheetah 63mm. Im spooling up anywhere from 1800-2000 through 3rd, 4th, and 5th. I want more low end power/torque. I hear smarty is the way to go if thats what you're looking for. Seems simple enough, but what else is going to be necessary for this truck to be reliable? Fass, clutch, pillars, and what about injectors? Will the smarty play hell on stock injectors? Im somewhat new to this and need real opinions and not some salesman trying to sell me his product.
