Because we still get phone calls every day asking for information about Dr. Performance power modules, we wanted to let you know that they went out of business in the summer of 2011. Questions we are most often asked include “How do I get warranty work on my Dr. Performance module that I bought a few years ago?” and “Do you know how we can get in contact with Dr. Performance?” The unfortunate truth is that they are completely out of business, haven’t answered their phone in almost six months, and any repair work on a damaged or faulty Dr. Performance module at this point is impossible.
The most frequent question we hear from customers interested in a diesel performance module next is “Since Dr. Performance modules aren’t available, are there any other manufacturers of diesel power modules?” Thankfully we can answer in the affirmative that there are several companies that make diesel performance modules that have the same beneficial characteristics that Dr. Performance modules had. Some of the reasons Dr. Performance modules were so popular included improved power without increased operating temperature, they were great for towing, and they gave substantial diesel fuel mileage improvements. They were also widely used as a trustworthy pressure box by diesel owners who wanted to “stack chips.” It didn’t hurt that the majority of them didn’t leave a footprint in the vehicle’s ECM because they were simply rail pressure boxes that uninstall quickly and cleanly from the rail pressure sensor harness.
Depending on the diesel truck you drive, we recommend a power module from two different manufacturers. If you’re looking for improved 6.4L Ford Powerstroke performance, we really like the TS Performance Power Play MP-8. On the 6.4L Powerstroke, the MP-8 is a fuel pressure only power module that adds up to 100 Horsepower and installs in just minutes by plugging in to a 15 pin fuel sensor connector. Just like the Dr. Performance module, the Power Play MP-8 doesn’t increase your diesel exhaust temperatures and most users report gains of 2-4 mpg in fuel economy.

For common rail owners looking for improved Cummins diesel performance or Duramax diesel performance, the Digi CRBB Power Module from DieselPower has quickly become our favorite choice here at Parleys Diesel Performance. Backed by an unheard-of 3 year manufacturer warranty and built from some of the best electronic components available, the DieselPower Digi CRBB is easy to install, doesn’t leave a “footprint” in the truck’s computer, can be adjusted quickly to any desired power level, and adds a decent amount of horsepower.

Because the Digi CRBB is a fuel rail pressure module it can be “stacked” with a Smarty programmer on the Dodge Ram Cummins diesels yielding loads of power that you almost have to feel to believe. Operating temperatures are kept down, and if you don’t drive the truck like you stole it fuel economy can be improved significantly. The Digi CRBB is also effective for “stacking chips” when using EFI-LIVE tuning on your Chevy or GMC Duramax diesel. If you have any questions about these or other options for your diesel truck, call us and we’ll be happy to help.
