Proven Diesel is by far the most consummate tuner you could possibly work with. Labeling Proven Diesel as a 'tuner' fails to do their brand adequate justice, as this is a full blown operation that far surpasses your ordinary Joe playing around with strategy tables in his garage and selling tunes through FB marketplace.

I ordered the limited support pack from Proven Diesel for my 2019 Ram 2500. Set up was very easy and download was very quick. Performance of the tunes have been good so far. I feel I will be purchasing the full support package in the future.

Hands down the best customer service I have dealt with in years. I'm in the states and the guys took the time to explain thing in detail and making sure I was all set and never rushed me off of the phone with them. Truly appreciate it.

Completely satisfied with Proven Tunes and EZ LYNK on my 2016 F250 Power Stroke. The customer service for answering questions and tune adjustments is top notch! I highly recommend them!

I couldn't be happier with this company. First off, the customer service is awesome! The truck is an absolute beast and it shifts great. Tons of options to choose from and very little wait time. Thanks again!
