Factory tune

[Yngdmax92]

Can anybody help me out, I need a factory tune for a 2003 lb7. It's acting really really weird and I need to put it back to stock to see if the problem is still happening.

Again 2003 lb7

I have one at home for a CCLB, LS, Alli, what OS do you need?


I will have to get it tonight if your interested.

Look in the tune library. There are many listed there

I have a couple I can send you. 9044os?

That's the only one there is for 03/04, the problem is how many different segments there are for them, and they must be correct for 03-05 if you want everything to work.

That's the thing, I don't even know if the original ecm file is in the truck. I need to locate that. Could I go by the bin some where ?

Just post the specifics about the body configuration and somebody will have something

You can enter the VIN on calid.gm.com and it will tell you what OS and segments it should have. Post that up here and hopefully someone will have what you need.

If you're close to central Florida I can flash it for you to bone stock with my Tech2. If I had a spare ECM I could flash it, then read it out with my V2, but I know not to put the Tech2 to my 01 ECM that's been flashed to an 02 as this will brick my ECM(01 ECM's are fickle pains), and all the local yards want $250+ for an LB7 ECM.

2003 ccsb, 26 gallon tank, Bose leather, no sun roof.

I'll get the VIN as soon as he gets back in town, he works out of town.

This is from a 03, CCSB, bose, leather, push 4wd truck. It should work just fine.
