The only reason I didnt like doing that is the time it takes to make runs, download/emails logs, get a new tune back, upload, new log, repeat, etc. All while having your fingers crossed that the tuner didnt miss something and it runs fine on each run
Devin made about 15 short runs with my car on the dyno until he was comfortable making a full run and fine tuning it.
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.
