Don't get a superchip for this truck, that is a scam. And as far as power upgrades go, you will spend a lot
of money to get very little extra power out of this motor. With out turbocharging, the max you can hope for is maybe 30 more hp, which is gonna cost thousands to do, not worth it to spend that much to go from a 14.5 second 0-60 to a 12 second one. If you're looking for a puchy ride, you got the wrong truck. And though some mods may give you small milage increases, they would take decades to pay for themselves. I say start yourself off with a small suspension lift and a locker, then romp the crap out of it (this is what I will be doing/have done).
Pick up a Magnaflow or (if you want to spend a couple more bucks and get something slightly louder) Flowmaster muffler from your local pep boys, and maybe a little larger tailpipe if you want your truck to sound better. Then again there is also the always available 30 dollar Cherry Bomb glasspack, garunteed to be loud enough to piss off the neighbors.
Other than that, give 'er a really thorough tune-up, including all filters, ignition parts, PCV valve (which may be a biatch to get out
), throttle body clean-out, valve adjustment, and a good dose of Seafoam. That oughta give you 2 or 3 more HP and 1 more mpg
. Then leave the hp mods for later (or maybe never.)
Just echoing what I hear a lot on the forums and from others, as well as my own experience.
