I returned my car back to stock, other than the headers & exhaust. I had the tune returned to a stock tune, tweaked to turn off the egr & fix the O2 sensor codes being thrown from the headers. Will I be able to sell the SCT tuner now? Or it can't be used on another vehicle again unless the STOCK tune is on my GT500? I'm not sure how it works so any input will help, thanks.
