I bought a used Delta chip from a friend 0ff an 01 mustang Gt. I put it in my 02 mustang Gt and the car will not idle with it, i have to stay on the gas to keep it running. Any ideas what i possibly did wrong or why it not running right. We have the same mods done to both of our cars but he is running 87 octane and i am running 93. could that make it not run?

You will need to have the chip burned to your specific ecu code. It will not work properly otherwise. Any Diablosport dealer with a Delta burner can do this for you.

how much would a rough estimate be to reburn the chip to 93 octane to a new ecu code. also... do you get better or worse gas milage out of the chip?

Your local dealer will set pricing. The new tune should provide a gain in mileage.

Thanks

how much rear wheel horsepower do you think i will get out of the chip with my mods and running 93 octane.

depends on what files are available for your ecu
