Anyway... Who did your tuning? Do you have a FPR? How long has it been since your injectors have been serviced?? Need more info.

Check everything that has anything to do with the fuel system. (Everything from the fuel injectors back to the fuel pump.) Can you post a video or anything??

If this is the case... You should have a decent case on your hands. Unless you carelessly pumped your gas.^

I don't doubt that this has happened... But it seems highly unlikely.

Go back to that gas station immediately, get some of that "premium" gas in a can, and do a little testing. You'd think that station would have been confronted ASAP.

i was close then. i didnt think it would be anything serious. not very many people who have these cars drive them around if they arent really that nice... lol and i agree with them. you should go after them. think of what that could have done to your car..
