C-ISX installation
  • How our product will change your engine.

    Our product is an electronic chip that utilizes programs in the ECM to in fact stops the EGR function. Now, with our chip plugged into the system you will see a big difference in the engine performance. You will see it stops the Hesitation, Surging, Coughing, Black Smoke. The engine will have less vibration. there will be more responsive power for the fact the turbo lag goes away. The Horse power increase will be around 75. (which is lost through EGR). A 5 to 7 pounds of oil pressure increase & cleaner oil. No engine light will produced from our chip. Also see a MPG Increase in most cases because of the fact the hotter energy burn and having to use less peddle to get the same effect as before. Engine runs cooler up to 20 degrees because there is not hot EGR flow going back through the engine as before. More mileage between oil changes for the fact of cleaner oil. You will notice that when shifting the engine fall slower and it is easer to get it into gear. Engine runs as pre EGR. Fits on 2003 through 2010 trucks with C ISX engines.

    Our product is called The Ugly fix™. This chip will fix all the ugly things that the Cummins engines with EGR's do. It's built with high grade components and sealed for all weather conditions. Easy installation, and can be installed in about 5 to 30 minutes. We have stopped the nightmares of the Cummins EGR engines.
    Please keep in mind, this product will not fix a broken EGR valve. The valve must be working and clean (not stuck or sticking) in order for our product to work properly.

1 of 5 387 Pete with Cummins ISX Didn’t work. January 16, 2022
Reviewer: Jim Kennelly from Bonaparte, IA United States  
Installed as directions stated, check engine light out. Shifting through gears under load truck smoked and coughed worse then ever CEL would come on and go off, finally stayed on….tremendous lack of power. Removed ugly fix, cycled ignition, CEL light out. Turned on ignition to power EGR closed disconnected EGR wire, truck runs great again…. however I have a CEL light due to EGR wire unhooked. The UGLY FIX did not work…. hoping for a refund.

3 of 5 device just stops working November 24, 2020
Reviewer: Me from United States  
This is the second truck I’ve purchased one of these for, I thought the other truck was a fluke when it’s not working after four or five days BUT it was not a fluke.   They were  more than happy to  provide a  refund though.   all in all,  don’t waste your time or  effort as it’s literally  a joke and a waste.

5 of 5 Egr module for isx April 3, 2019
Reviewer: Terry Hamann from Hudson, WI United States  
I’ve had 2 of these modules and both worked fine for a short time. When it operated correctly my fuel mileage increased from mid 5 to mid 6 mph. Very impressed but both only lasted approximately 3 months and then they stopped working. Reason I know is I ran a check on the computer and it would say that the egr was operating the way it should and not in the shut off position.
