Titan XD Full Support Proven Diesel Tunes. Haven't had any issues and the tunes are clean with a TON of power. Great customer service. Highly recommend!

James H

I absolutely love these tunes. Did a 366 mpd turbo kit and the first tuner couldn’t get me a tune that was driveable for over a month and finally ignored me me. Proven listened to what I had and got it right on first tune. Don’t be scared to buy from proven you won’t be disappointed.

Jeff S

Bought a 2012 F250 Super Duty with SOTF tunes and shift on the fly knob. Didn't know **** about any of it. Couldn’t talk to the previous owners. Crawled under the dash and stated writing down everything on the black boxes. Intake housing was aftermarket and the exhaust was also. Had an EGR delete too. Didn't think it would do any good but I called PD. Well they answered me right away with everything I asked about. I’ve emailed him two more times with other questions. All answered accurately and promptly. Great customer service. Hell, I wasn’t even a customer.

Martin B

Installed tunes on both 2014 and 2017 F350 diesels. Tunes have worked great and I have had no issues. Proven Diesel is very quick to respond to any questions. I would recommend them to anyone looking to tune their power stroke diesel truck.
