Customer Testimonials

Noah Shaw

I have a 2016 Ford F-350 with the 6.7L. I pull a fifth wheel and the Dr performance module I installed makes me forget that it is behind me. It has made pulling my fifth wheel am absolute pleasure.

Great product! There is a noticeable power increase and the turbo lag is almost gone. Time will tell on mileage but I started a new trip after I finished the install. I did a test drive and noticed a 3 mpg increase over the trip meter I had going for the current tank of fuel. Again, great product and great customer service! They stand behind their product and take care of their customers. I would buy again!

Got one for my '13 Cummins I use hot shotting. Really woke the truck up. So much more power in the lower RPM range. Way easier passing on the interstate. Gained about 2mpg as well.
