I had an ARD tune on my R. Ran great for a few days holdin 20-21lbs of boost. Days later got 25 lb spikes, car started running a little rough. Few days after, car ran very rough. Got a cel light, car ran like shit. Had to have it towed to my dealer, opened the ecu, found melted parts. had to buy a brand new ecu. I'm not getting another ARD tune. i would stick with IPD, Elevate, BSR, or whatever Viva sells. That was my experience with the ARD tune.
