Tuner for me. Most enhanced horsepower and versatility to adjust the parameters of your engine to expand the performance possibilities. Aside from the fact, it's just cool! (Next was exhaust...if I can have 2 :str
Interesting... since this is my daily driver, most of my mods have been towards comfort and drivability. Next things on my list (other than audio) is to improve the handling and nighttime visibility.
My favorite out of those is def a suspension lift, but all those modes work together you cant lift it and put big tires on w/o some extra power so ya need the cai and programmer but those wont be much help w/o an exhaust to free up some air my last truck and my plan for this truck is finish up the little things like the Mopar grille badge im working on and my blue lights then exhaust,cai,programmer lift or leveling kit depending on fund bigger tires and some sort of light bar and lights in that order possibly regearing from 3.92 to 4.10 or 4.56 as well
Exhaust is always the first thing I do also. This is the first used truck I have bought in over 10 years some of the other fun stuff has already been done. FIPK and leveling kit was already on the truck and I put on the bigger tires cuz they look cool (and ride better than the rugged trails). Now I'm taking out the leveing kit and dropping down to a 295/70-17.
I have always heard the best bang for the buck is a tuner. If I am running like a BOH, I do not care if your truck is lifted, or laying flat, it all looks the same in the rearview mirror,lmfao
even though mines still stock, and might be so for a while, i vote exhaust. The tune is a close second, but i think a tune should be done after bolt ons. And a good exhaust makes the truck sound like what a truck is supposed to sound like.
