    Yeah. One of the guys here got one and it turns out that his engine already had a tune on it. Sure you had the stock programming in the ECM you had?

    I posted in the other thread where you asked this question.

    I think someone forgot to check the rating number afterwards. If it changed during the tune and they didn't catch it. You probably only have 200 Hp
