Well, I was out crusing the town tonight and using the 140a(too much fun), and then I raced a ford mustang in the 120 tune. And then when I came home, I put it over to stock tune and thats when the check engine light came on, but it doesn't come on in any other tunes. I didn't look at the boost gauge, but is this a symptom of overboost? I do have a overboost annihilator coming in, but I'm just curious on what could have thrown the code. I will get it checked out tomorrow, just want some opinions on what it could be. Thanks in advance.

 

you will get the over boost code when you are over boosting..get the code checked and come back to let us know..you can find the codes in my sig using the DTC link...
