I'm wondering to what extent(if any) the computer in my XJ can be retuned. The reason I'm curious, if it is, I should be able to change the shift points, right? I was helping a buddy out on Saturday with his F350, and he had another guy come by and retune his computer with one of those hand held deals. It made a huge difference, it shifted later(good thing), it had way more low end speed(another good thing), and actually ran a little cooler(a really good thing). He put on new exhaust, a jet chip, bigger tires, new gears, and the retune really brought out the best performance from the engine. Now back to me and my XJ. I'm running 33's(35's sooner than later) 4.10's, and will be doing a cat back with a flowmaster delta II. I'd like all of these changes to perform as well as possible, and retuning the computer would help, wouldn't it? When it comes to the computers on vehicles( or actually any computer) I'm more than a little in the dark, I'm fully on the dark side of the moon, I know nothing. Any info( as always) would be appreciated.
Thanx,
