I bought a tuner and it states engine damage may occur if you try to tune over aftermarket tune. How do I make sure it is a stock tune? It is running about 15psi boost. previous owner left some goodie on truck but since it only ran 8.80 in the 1/8 i assumed it is stock tune. Any advise would help. Thanks

 

OK, I hooked up a Pedator that I purchased and it said it already had a tune. Now to find out how to find out what it is or how to delete it. Any thoughts?

 

Contact the previous owner to see if they still have the programmer that was used on that truck. Or, at least the brand that was used so you can contact them to see what can be done to unlock the ECU so you can use your programmer.

 

I would except I purchased it from a dealer.
