I'm looking for a 2002 PCM and some 00+ injectors to upgrade my 99 model.
Thanks

 

sorry to jack the thread but this is the 3rd or 4th truck I see upgrading the pcm. What's the deal?

 

99 PCM has a problem with false knock.. really makes these trucks run like crap....

 

What is involved in the swap?

 

Yeah, the 99 PCM blows goats. PCM is easy to change. Just unscrew the 2 connectors on the PCM and then pop the PCM loose. Pretty easy. But then you have to do the security re-learn. That is what takes some time.

 

Jared, now I see why you said the 99 pcm has "Gremlins" inside.

 

Hey smiths_3 I have some injectors from a 01 2500HD 6.0L. They will work in yours! Let me know what you can offer! Thanks!

 

Yeah, it was a pain in the ***. Hopefully when Allen updates it in July it will solve the problem. AND so I can get the use of Edit back.

 

I've got some 01 5.3 injectors with around 40000 miles on them.

 

I've got a 99 5.3L. What is the security re-learn, is there any down time when doing the swap (basically just un-bolt the 99 and drop in the new?) Right now I have the HPP3 installed, would my truck still run better if I swapped out the 99 HPP3 programmed computer for a stock 01-up computer? Does a newer computer really make it run that much better?
