Hello, i got a 2005 F-250 with a 6.0L diesel and i would like to reset the computer in it if possible. I had a SCT tuner in it and just wondering since i returned the computer to stock and am getting rid of the chip, is there any way of reseting the computer to get a better chance of not leaving a fingerprint of a chip??? I unhooked both batteries both + and - and i will let it set for a couple hours. Anything else to try?? I was told that my tuner would not leave a fingerprint but i just dont want to chance it. Thanks!
