H&S Mini Maxx Race Tuner

The Mini Maxx race tuner is part of the next generation of diesel downloaders from H&S that offer everything a diesel owner could want, all in one high-tech unit. 

H&S Mini Maxx Race Tuner w/o Pyrometer Connection – Shift-On-The-Fly Power Levels from Stock up to 275HP

The Pyrometer connection is NOT necessary for the H&S Mini Maxx without Pyrometer to function correctly. It is used for gauge display and for one of the defueling parameters. It will NOT harm your truck to run without a pyrometer probe installed. We do, of course, recommend purchasing one for the 6.7 Cummins and 6.6 LMM Duramax so you can monitor your Exhaust gas temperatures and set your defuel levels based on EGTs. Ford 6.4 Powerstroke trucks can use a factory sensor in the manifold to monitor EGT.

The H&S Mini Maxx without Pyrometer Connection is capable of disabling emissions equipment. If using DPF/EGR removed tuning, this H&S Mini Max without Pyrometer Connection is intended SOLELY for closed-course racing use and is not street legal in ANY state. This H&S Mini Maxx without Pyrometer Connection cannot be used on any vehicles registered or certified for highway use.
