Just wondering if any one can give me some advise on my ecu . I brought my S2 3years ago it was running 14psi. had the engine rebuilt this year and went to have it set up but tuner recons it hasnt been chipped.He told me to take a look at the ecu and take it a part to see if it had code or a tuners name or initials in it . took it apart and it had ford waranty seals on the side and told the tuner it has not had the warrenty seals broken but wanted to ask for a second apinion first as he said i need a chip please help
