Can you give me some more details? What year is the pcm? Are you talking about an EARLY 99? If you are, it will run. The engine is virtually the same except the 2002 has PMR's, 17 hpop, AD injectors, and a few other things. Your engine is just detuned in a round-about way. If you have a 1997 or older pcm, then I will definitely need more info!

im assuming the computer is a 99 it dont look like its been messed with. well the truck is made in like 4 of 98 but its the new body style. but ya pre 99.5.

it runs and drives iv drove it for quite some time now. it just doesnt seem to run as smooth or as much power stock(chip gives it a little more of coarse)as my dads 02 truck. wich has the same year motor in it.

4/98 means that you have a 1999 truck. It's an early 99. I will run fine, it's just detuned.
Find a used PMT1 (or any PMTseries) pcm. Truck will run better and the trans controls will be much smoother.

The 402 is the old pcm. You need to upgrade to the 422. THe PMT1 is the best. I had the XLE4 in my truck before I replaced it. Also, with the 422 series, Jody (dp tuner) or Tony (wildman) will have a wider tuning ability.


In short, the xle is junk.
