You have 20+ engine paramaters including transmission temp, boost, intake temp, fuel rail pressure, exhaust gas temps and a bunch more.

H&S Mini Maxx Race Tuner DPF and EGR Delete

The H&S Mini Maxx is one of the few tuners on the market that will completely disable the DPF/EGR on your truck. Disabling the DPF will allow you to install a DPF delete pipe and eliminate the very costly to fix DPF system. This is a great added benefit to you as the DPF is known to cause costly breakdowns, lower MPG and significantly reduce performance, if you’re interested in doing a DPF and EGR delete but don’t know where to start take a look at our DPF Delete Parts Round Up.
