Yo, so for some reason i cannot find my stock tune file on my computer, lost it somehow. I went to the repository and found 1 2004 GMC Sierra 5.3 stock tune, and i used that but the truck idles rough and i just don't think it will work. So if anyone has a 2004 silverado/sierra 5.3, doesn't have to be 4l80 just the stock tranny is fine, i need a bone stock file. Also, if it's OS 12587603 that would be great. Trying to put my truck back to stock, so just need to set the engine part to stock, still have the 80 in, so if anyone could post up or shoot me an e-mail and send it to me that would be great.

 

2wd or 4wd? I have quite a few with the LQ9's and I think a couple LM7's, but I do have an LQ4 file with an 80E that would be easy to convert to a 5.3L and already have the 80E calibration in it.

 

2wd, no i just need a stock file, i know how to do a segment swap, that's no big deal. I just need a 2004 GMC Sierra/silverado 5.3 4l60 2wd stock bin.

 

BUMP, i need something, i just put the stock fan on and reflashed this file i got on the repository and it almost dies on me at idle. I know it needs some mileage to get alittle better, but still it's pretty shitty right now. I hate the fact i don't have my stock file.

 

I should have it. What is your email address?

 

I know this thread is old, but I need an 80e file with the same os number, 12587603, if anyone still has one...hptuners preferably...

 

Obvious question , but did you try the HPtuners forumn?

 

Yes, and the repository
