Don't just slap the cheapest tune you can find (which won't be cheap, anyway) onto your $20k (+/-) car, unless you're also ready to go looking for the cheapest turbo, long block, etc. that you can find. Your best bet is a friend with a Cobb AP (they'll need to unmarry, before flashing your car).
What is the problem with the car? Can't be the stock tune. So you must already have another tune, right? Why not flash back to stock to see if your issue goes away?
TLDR: Need more info.
