VMP tuned my 08 GT500 and my 2013, Justin has always done a amazing job with driveability and making sure everything is safe. He emails me a tune and I do a quick datalog to make sure everything is spot on and I'm all done. Devin did a shit job tuning my 08, he spent 6 hours trying to tune it, than told me it was all good, and on my way home the car barley ran, Justin sent me a new tune and the car was perfect again, I personally wouldn't let Devin tune my lawn mower. I promise if you guys go through VMP or Lund or even Bama you won't be disappointed. Email tuning has come a long way and there are some amazing mustang tuners out there. Unfortunately AZ just doesn't have any great mustang tuners.
