When I installed the FPP tune on my truck, while it was writing the blocks it also flashed erasing. Is this normal? Is it erasing the stock tune then writing the performance tune? Has anyone else noticed this
Also something to be aware of, because of the tune your transmission will have to relearn itself and you again. It did this to me with the Livernois tune and after a few thousand miles everything was all good. Just some helpful information for you.
