Dorman 904-107 Tuning Calibration Resistor for Chevrolet/GMC PMD No.5 and No.9

I recently replaced the diesel fuel injector driver module resistor on my Chevrolet pickup with a Dorman part, and I couldn’t be more satisfied. This component has made a noticeable difference in the performance of my truck.The installation was straightforward and hassle-free, even for someone who isn’t a professional mechanic. The part fit perfectly, and the detailed instructions made the whole process smooth and easy.Since installing the Dorman Module, my truck has been running much more smoothly. The engine performance has improved, with more consistent power and better fuel efficiency. I’ve also noticed a reduction in the rough idling that I was experiencing before the replacement.Dorman is known for their high-quality automotive parts, and this one is no exception. It’s well-built and designed to last, which gives me confidence that my truck will keep running reliably for a long time.Overall, I highly recommend the Dorman Diesel Fuel Injector Driver Module Resistor to any Chevrolet pickup owner needing a reliable replacement. It’s affordable, easy to install, and significantly improves vehicle performance.

Worked very well. Price was good. Arrived in time

Watched a YouTube video after replacing my pmd twice , guy said to run these and I’m glad I listened, truck runs better than it ever has . Great product and works as intended! Highly recommend !

I am using both under hood, 2 pmds one for summer one for winter, truck starts better with the 9 but gets better millage with the 5 resister. if truck breaks down while wife is driving it she won't need any tools if pmd, just unplug from 1 and plug into the other and keep going about her business. I'm still waiting for the day she fills it with wrong type of fuel, because some things can't be fixed:)

Used the #5 in an Amazon special PMD relocate kit. And 2000 miles later it’s still working great. Zero issues. Would buy again no problem.
