Just got a new 03. Installed a K&N kit Yesterday. Don't notice the 9Hp Gain, but it does sound a little bossier with increasde resonance and air noise. What should I do next. I'm looking at a new muffler, not necessarily an exhaust system, unless it will really provide some low end grunt. Which programmer will give the best Bang for the buck. I feel that it has plenty of Hp, but needs to stay in gear a little longer without mashing the throttle. I would also like to see it kick into passing gear when I mash the throttle on the highway. I came off of a 97 powerstroke and am kinda used to torque and not Hp. I'm getting used to it but really am looking for some off the start gains. Does this truck posess the capability to cut loose from the pavement without going to some sort of supercharger?
Thanx
