Hello, im doing a build cobra swap with a return system on a 02 mustang gt with a th400 swap, my question is when I take my car for tunning do I need to break in the motor before the tunner goes balls out on the motor or should I tell him to give me a base tune, drive it for a while then after some mileage on the motor take back the car for a final tune?
also, can I turn the car on if the car was returnless and im going return without a base tune, im eliminating the fprs.
