    P0244: overboost. You mentioned you had a boost spike. Basically, the ECU has a limit as to what boost to cut out at, and you hit it.

    P1088: TGV #1. PS Front. Make sure the connection is tight/secure.



    After checking the connection for P1088, reset the ECU and see if the code comes back.

    would the tgv be causing the loss of power??

    TGV codes cause the car to go into limp mode. That's why they are disabled when you do TGV deletes.

    I'm having similar problems still.

    Reset the ECU, runs good for a bit then set back to limp mode. When i reset it and it boosts properly, there's a slight rattling noise. Thinking this might be part of the problem, but no CEL's are thrown.

    Also, replacing the catted uppipe tomorrow, hoping this will solve my problems.

    Could cleaning the MAP sensor help?

    Just pulled the negative battery, drove it for 25 minutes. Limp, just like that. It's driving me mad! Any suggestions?

    Do you have TGV codes?

    No I haven't ran any codes, figured since I'm not getting a CEL I didn't need to. Maybe I should stop by Autozone and plug it in? (I'm still pretty new at maintaining a forced induction motor)

    Also, thinking i might have just had some bad gas, maybe try some octane booster. Start with the little things first, right?

    It bounces back and forth on it's own, runs good for a while, then sets itself back to a weak mode. I can pull the battery and it will run strong for awhile..until it sets back again. Anyone ever heard of anything like this?
