Dan's Diesel Performance

Here is a little background on who we are and what we do. We're located north of Marengo IL. Half hour east of Rockford and 1.5 hours from Chicago. We specialize in Duramax, Powerstroke and 5.9-6.7 Cummins. We started in diesel performance back in 2006. We sell and install high quality name brand performance parts and accessories. We also offer repairs and maintenance for trucks as well. On the tuning side of things we have been custom tuning Duramaxs since 2009 and Cummins since 2011 with EFILive. We're part of the EFILive Beta team and help to make the software possible for the end user. For the Powerstrokes we use SCT to write our custom tune files. All our calibrations are made in house. We have our own Dynocom DC-1800X load cell dyno on location for tuning and testing trucks performance. Our dyno is also mobile which allows it to be transported to events. We offer engine and transmission builds for any application from street truck to all out competition. If you have any questions please feel free to give us a call or shoot us an email.

Hey Dan!

If I had a truck to spend money on with a fancy computer, I would take it to you guys. I have seen your work on the dirt and asphalt. Top notch and have never heard anything bad about you guys.
