i have had 2 sets of tunes emailed to me from bama custom tuning. the first ones made my car ping like hell. my second set of tunes seemed ok so i thought. the race tune seems alright but my 87 octane street tune is junk. loaded it on the car, it makes the exhaust so hot you can smell the paint cooking on the mufflers and then yesterday it made my engine go into failsafe mode. i guess thats what you get though when you go the cheaper route. ill be paying the 300 bucks for dyno tunes from now on when i make modifications to the car so i know its tuned properly. email tunes are junk
