I recently purchased the Dr. Performance Module for my 2016 Ram 2500 and I love it. At +60hp I noticed a decent increase in power early and a smooth ride. At +100HP It is a new animal. It accelerates at the rate of a sedan! It. Just. Goes. Hardly any turbo lag!

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!

I recently put a Dr. Performance Module on my 2016 F250.

The fuel mileage while towing is night and day! Plus the bottom end power is awesome for taking off with a heavy load!
