Just put the Dr. Performance module in my 2019 Chevy Duramax cab and chassis and definitely a noticable difference.

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!
