Does anyone have the stock OEM PCM tune? I need to take truck back to stock from the tune that's in it.

Thanks in advance

I looked thru the ones that were there to see in any close matches, they had 4.10 gears , 3.73's but nothing close to the 3.42?

Worst case you'll need to take the closest base tune and change the gear ratio/tire sizes. If you want to be BONE stock and can't find a tune, time to break out TIS2Web and flash the PCM with the latest calibration for your VIN.

thanks, went thru it and trying to figure it out. It gets me to almost the end but then doesn't let me download the file needed.

Thoughts?

I have a stock 05 Avalanche 4x4 tune with 3.42 if you want it. Isn't the same OS as yours but you're welcome to it.
