When I heard your car it sounded like a cement mixer truck, it was loud. Its too bad that this guy has screwed you over, I would try to take some legal action.

 

it had 4 cylinders at the time lol... truth be told i actually dont know how my car will sound like wen i get it back cuz iv never had the car working with all 6 cylinders.

 

small claims court is the way to go, I went through a very similar situation, shop tuned my car poorly, using a dyno, TT 350Z, when the car wouldnt stop smoking on excelleration, the shop told me the motor was done, I took it, and the dyno sheets to a different shop and it was clear it was the tune, all I wanted was an apology, no such thing, I took them to small claims court and settled at the mediation...somtimes you just have to take legal action, esspecially with a cocky ***** telling you he will charge you double to fix his mistake...

I use a different shop now, quite a bit further, much worth it, and I make it no secret how I feel about the local shop...

Good luck...
