It was nice that I didn't have a tune married to my car when I traded in my 08, I put it back to stock and flashed a mild stage 1 to it. Whoever bought the car got the best running "stock" 08 on the lot. LOL
FYI, when you download the map from the car to Ecuflash, you have to tell it NOT to save a copy when you close the program kinda like microsoft word. So if you flash a new map and never save the original...it's kinda the user's fault. LOL
Another thing to consider is that the AP acts as a multi gauge too I am told, and you have to carry a laptop to get that with OS, or run an ipod touch with kiwi wireless like I do.
