I have an 02 LB7 gmc that I tuned and runs great fine whatever so today I go to to do the DSP 5 for the guy and I install the switch and as I always do I check with the scan tool that the switch is recognized and switching and it was so I button the dash and fender well up start the rig and pull outside and am letting it warm up and it shuts off. restarts fine and then about 90 sec into idling warming up it does it again. so this time I sit in it and let it idle and when it does it the battery light in the info center comes on, Now if I hold the throttle at 1500 rpm when it does it cuts out but it will catch it self and continue to idle and come back up to the 1500 rpm, So I Full flash the single tune I built back in and it idles for 20 minutes with no issue, I also re full flashed the DSP5 in and used V8 this time and still does the stalling thing. Any ideas?

You have a bad file, you need to flash it back to stock with a Tech2 and start over from scratch. I have seen it happen myself a few times in the past.

I started out with a single tune and then changed it to a dsp5 OS built the tune and full flashed it in guess I could make a script of this and run it over the new tune cause this is the LBYLL7 truck I've been working on lol

So there's no way I can get a known good tune of the same OS and flash it in withy mods? Has to be from a tech II?

mark, if he doesn't have access to a tech 2, could he just download a stock tune that's clean flash it and start all over?

You could try but I don't ever feel good about that, always know your good if you start fresh when you have an issue like this. Figures it's that truck, lol!:spit:

ALL 01-02 trucks I do get the same 6006 OS I run in my BURB. I just set the appropriate tables for tank size and such and use it as it is a known good file.
