H&S Mini Maxx V1 For GM/Chevy 6.6L Duramax 2011-2014 | Delete Tuner
The H&S Mini Maxx V1.0 delete tuner for 2011–2014 GM/Chevy 6.6L LML Duramax is a handheld device that kills the emissions codes and gives you four power levels — preloaded, plug-and-play, and ready the day it lands on your doorstep.
It plugs into your OBD-II port and reflashes the ECM directly, so there's no shipping the ECM anywhere and no laptop software. The delete tune shuts off emissions monitoring across the board — DPF, EGR, DEF, CAT, SCR, DOC, and EGT — so the truck stops looking for hardware that's no longer there. You do have to physically remove the DPF, and EGR removal is optional but highly recommended for the best reliability.
In the box you get the Mini Maxx V1.0 with all required cables and accessories, the DPF delete tune preloaded on the device, and official installation instructions. Once it's in, the Mini Maxx stays as a permanent gauge display — a hi-resolution screen that tracks up to 20 metrics, shows up to four at once, runs automatic EGT-based safety backdown, and handles speedometer calibration for aftermarket tires or gearing.
The four power levels run Stock, +60HP, +120HP, and +175HP. There's no shift-on-the-fly, so you change levels by re-flashing from the device. Owners report a 5 MPG increase on average once regen cycles and backpressure are gone. Fits LML pickup models — Silverado and Sierra 2500/3500 — but not Cab & Chassis. Returnable within 30 days if undamaged; restocking fees apply.
For off-road/competition use only.
