Installed one in my 2020 Ram 4500 service truck that's loaded down and now it accelerates much faster and MPG has gone up 2 and still climbing. Great product excellent customer service would definitely recommend.

Dr. Performance is amazing!!! I want to start by saying best customer service I have ever received. The product is mind blowing. This woke up my 2003 dodge ram 2500. I highly recommend this product BUT IF YOU HAVE ISSUES WITH YOUR TRUCK GET THEM ADDRESSED BEFORE YOU BUY THIS. It will not fix a broken truck.

2015 f350...installed the pro mod in 15 min, not to bad for a cabinet installer. Very happy with the fuel economy, hooked to the toyhauler or not. Thinking injectors in the future and will definitely be ordering from them!

Best diesel performance accessory shop around!!! Love these guys!! The module was easy to install on my Cummins. I noticed a better power curve and a lot better low end but It took a little while before I started seeing some mpg gain but now it's giving me a couple more mpg. Super happy with the product! Thanks Dr. Performance!

I installed the pro performance module on my 14 6.7 and she rips now. Turbo lag is all but gone and the bottom end torque management is significantly better. I can hardly feel the toy hauler fully loaded climbing the mountain passes and I notice a big difference getting to speed on the highway on ramps. Also seeing about 3mpg increase without a load and I have a solid lead foot. Definitely worth the cost I m getting another one for the work truck.

"Heads-up warning about Dr. PerformanceRx diesel module and their advertisement of a 30 day no hassle money back guarantee".I first purchased the Dr. PerformanceRX module for a 2015 Chevy diesel and it worked great for fuel mileage and performance.So naturally I purchased it again for my 2021Chevy with the same expectations of picking up two miles + to the gallon better. However, that wasn't the case this time. In fact, I was getting two miles+ to the gallon less driving & towing a 17k trailer.The extra performance was great, but that wasn't why I purchase the module.Filling out the online return form and having the module back in their hands within the 30 day time frame after I received it, (sketchy) representative Annie, stated on June 30th that my refund would be processed after they had a chance to check the module out.That was 38 days ago, still without a refund and no replys back to any follow-up emails and now they've blocked my phone number after speaking with another representative, Will...They know they have an issue with the Chevy newer engines and don't want to own it.

Dr Performance ModuleHi my name is Terry and i have had my Dr Performance Module for alittle over a year now, and i just love it. I installed it on my 2017 Ford F-250 super duty, i am running 35x12.50 tires and reason got the module was because i lost about 3 mpg with my oversized tires. So when i installed it for the first time i couldn't help but notice that my truck just kept pulling and pulling, it just felt like there was no end to the power band, it was pulling all the way through my rpm range. I was extremely impressed. Then i notice an increase in mileage on the highway, now that it has been about a year the Dr Performance module has completely learned my driving habits and increased my mileage about 3 mpg. So now i am back to stock milage but with oversized tires. So not only more power, i get better milage, win, win!! I would recommend this Dr Performance Module to anyone who is looking for power and better mileage.

Waste of money. Cummins 6.7 2022 no change in anything. Says 4 settings and the knob only has three. No better performance or gas mileage. Just wasted $900.00.
