    one sad duck.

    my car is now running rough, ie lots of engine vibration and noises. At first i thought i had a low tire because of the roughness. but not so.

    no cel codes, and it doesn't actually feel like its missing.

    what should i do/look for?

    That was my response as well. Has anyone ever heard of an AP stg 1 or 2 map seriously screwing up a car? He bought my AP tonight and we flashed his car. Did several hard pulls in it and it felt great, but he called me on my way home with these symptoms...

    I'd bring it in and see what I can find.

    I remember after flashing AP, whenever you lift off the throttle quickly it didn't move the drivetrain around as much as with the stock tune.

    A mount could certainly have gummed up ?

    Did you flash a protune map or an OTS over the shelf map...i'm hoping the latter!

    When I saw you at hobbytown usa you said that it was already running rough...turbo surging and such, this was before the install of the ap right?

    Flash a stock map back on there. Might want to try cleaning your MAF sensor too.

    okay, possible resolution with Will's help...

    loose lugnut(s) on driver's side.

    Its much better, now. But Hey Will, could running it like that have damaged the wheel? or the tire?

    There was no damage that I saw. But...in the long run it could have messed up the holes in the wheel, damaged the lugs to the point where they could be be used, and the wheel come off.

    But...there was no damage.

    just got a change actually.

    Decided to try Lucas full synthetic. It was only a dollar more than all the other synths.
