Hey I'm looking for a reputable tuner in southern New Hampshire. I already have a tune on my '12 6.2L but I'm not that happy with it and the guy I got it from is far away and getting away from trucks and concentrating on Camaros and Vettes so I won't get much more future support.

Some basic googling has brought up 2 shops that are reviewed well but I'm curious if anyone has any experience with them or knows of other good shops. I found Performance Dyno in Loudon and Granite State Dyno and Tune LLC. Let me know what you guys think.

 

Both are good shops performance dyno does a lot of mustangs

 

If you're willing to drive, I highly recommend SMG motoring in mass. Fred tuned my car and did an awesome job.

 

pete at performance dyno is great guy he did my old 90 gt car ran awesome I've got no experience with granite state

ive had SMG do my truck freddie is also very good but its a hike for you
