Is a Pre 99 computer with 02 motor a bad idea?

[myredtruck]

hey guys. my trucks not quite up to par. its a pre 99 with a 02 motor 02 turbo as well. do i need a later model computer?

[wesjones]

you definately need a new computer. 02 motor? the motor was changed in 99.5 as was the fuel map, etc...

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!

[wesjones]

yeah ditto....if you have like a 95 then you may want to switch, but if its a 99.0, it will prly be ok

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.

thats funny you mentioned the trans controls my trans does shift alittle rough sometimes! ill give that a shot

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.

your awesome man thanks, one more question
do you know what years for sure have the pmt1? the only pcm on ebay is a xle out of a 2000, so like 01 and newer?
