Fits: 11-14 LML Duramax
From the leader of DPF Deletes and Code-Free Tuners, H&S Performance, comes the newly redesigned & versatile Mini Maxx Tuner / Monitor, for your 2011-2014 Chevrolet / GMC 2500HD & 3500 Duramax diesel pickup truck. Originally designed for closed-course racing, the Mini Maxx allows the removal of the DPF, EGR and EGR Cooler from the exhaust system — code free! The Mini Maxx comes with DPF-Equipped tuning modes as well. With four different power levels, experience rear-wheel horse-power increases from 40 up to 80 over stock in DPF-Equipped mode — and HP increases of 50 up to 150 without the DPF! Rather than resting on its successes, H&S continues to raise the bar with the Mini Maxx tuner / monitor.
