I can not express the degree of my complete satisfaction with my experience! I highly recommend you have your own. My 2021 Mustang GT motor is completely stock. Always a dream to own one of these. When I finally bought one it was nice but.....there were some issues. Ran better some days than others. Minor stumbles and nuisance misfire codes that the dealer couldn't/wouldn't fix. So I went to see Dan and the team at ProDyno. First because I wanted to see what the stock motor had (horsepower wise) and secondly hoping maybe some of those issues would be resolved. After the dyno and tune what I received in return is beyond my expectations! It literally is like a different car. What I thought was a well running, most of the time, Mustang was slow and lethargic. The vehicle runs great every day, under any circumstances. Hot, cool, makes no difference. The added bonus is meeting Dan and his team. I have never met more genuinely nice people in the automotive industry. No attitudes, no condescension, just really nice people. That goes for every single person I encountered. From passing a tech in the shop to Dan himself and TJ up front. Needless to say I have been back for other minor mods and will continue to do so. read more
