H&S MiniMaxx Throwing Code??

We did the update before we installed the minimaxx with delete. Since the install every time I drive the truck within the first 5 mins it says "Reduced Engine Power" When I go to clear the code it says Turbo/Supercharger Overboost Conditions. Anyone had this problem?

I would take memory card back to computer update card. Then re-install to your truck.

Make sure to update firmware when you put the memory card back in your mini Max when its in your truck, before installing the download to the truck.

I assume you have a 2013 or 2014 model? We have done some recent updates to address P0234 overboost conditions. Please update your device and let us know if you continue to have issues.

Thanks.

Got her 13 files updated and updated Firmware also. I hadn't tuned the Transmission before, but decided to give it a shot this time also. So far no codes.

If it doesnt work out for you and you are not concerned with all out speed and more for towing and reliabilty SPE made a custom tune for my personal truck and 2 of my fleet trucks , you can floor it all day up hill and the boost stays in a very safe range and ive never seen higher than 1200 EGT been running the tune for 18k with no hiccups
