Where in Oklahoma are you? My tuner is near Fort Smith Arkansas. There are a few in the Dallas area. Couple who do remote tuning. I read all your other posts and didnt see you say anything on where in Oklahoma you are.
Get the MPVI2 or MPVI3 with the Pro Link and don't forget an extra credit for the FPCM. Add another credit for auto transmission. The automatic transmission tuning is a must.Buy yourself an HPTuners MPVI and license your car to it. When you take it to a tuner, take your device with it so they can tune with it. That way if they ever go out of business you can still get it tunes without having to pay to license it again
