Ok, no cummins bashing, I didn't sell the dmax, I bought a tool biz, and the snap-on trucks come with a 5.9 cummins. Aaand, being a power junkie on a budget, I would like to know what I can do to bump the hp a safe amount. Tuner, new intake, what else? Or what are my options? Not looking to make the thing do wheelies while hauling toolboxes, just a wee bit more go and better mpg. Thanks!
