i have a 03 duramax lb7 looking for a stock tune for federal emissions any help would be appreciated greatly

thanks

thank you nick so much for link. does the dsp5 switch for the 04 lb7 compatible (my guess would be yes) with the 03, and how aggressive are the tunes.. thank you again for a base line to start with. glad to remove the unwanted gremlins that are required in certain states around the U.S.

The DSP5 switch is the same for all LB7's, yes. I can't vouch for any of the files in the directory. They're not mine, just a spot for easy base files for beginners.

Enjoy,

Nick
