Hello, i just recieved my diablosport predator for my 07 duramax. I have yet to install it, but needed to ask something. I installed a 5" exhaust stack kit on the truck and now im getting a check engine light. MBRP said some trucks do it and some dont. They said u can purchase what is called a finger stick and block the code from flashing. Can the predator clear this problem without buying that? The exhaust kit has been on for over two months and until yesterday it hadnt flashed the light. Its not miss firing or knocking. Thats the only thing i can think of being wrong.

Sounds like they are referring to your egr, thats what the "finger stick" mod is for. The predator can not eliminate that code. i would use the Predator and scan your truck so you can see what the code is for, it could be something not related to the exhaust.

heck yeah man. I just installed the programmer in my truck and man it rocks! I just had a question though. I installed the 85hp performance tune on it, then went back and changed my tire size to correct my speedo. Now the question i have is, In installing the modify stock tune to fix the speedo does it take the place of the performance tune i installed earlier or does it just add the speedo corrections to that tune? oh yeah, can u tell me if there is an update for the LBZ programmer? Thanks for answering.

The factory hp tune does not add any power.
You want to go back and modify then install one of the power tunes.
There have been several updates to the U7186, the latest revision is 1r19.

Thanks
