  I purchased and installed the Mini-Maxx on my 2009 Duramax. Took a 200-mile trip through the mountains of Colorado just before installation and got 19.0 mpg. Drove it the same way at the same speeds on the same road and after installation I got 25.5 mpg. Have not yet tried it pulling a fifth-wheel.

  This product is the best I have EVER used. The install and use give it the feel of a product that was made by people who also use it. Very user friendly and PACKED full of every function you could want. Can't wait for the nitro/meth support.

  First time diesel owner. Bought the 2010 6.7 Larimie with 35's. Programed it with the mini with just 1300 miles. Milage went from 12-14 to 18 in town and 23.4 interstate. WOW!!! Amaizing product.. You can't own a diesel and not wake it up with H&S. Wish the trany tune were a little cheaper after purchasing the tuner though.

  I have found that it is really easy to depress the lock tabs on the side of the OBDll connector, then turn it around pointing up and install the plug facing upwards under the dash. Very very clean install method keeps knees from bumping the plug on entry and exit of vehicle!!

  This being my first install of H&S Product it was a quick easy install, tuning seems to be pretty good. would like to see the OBDII connection a little more out of the way also Instructions could be updated but under stand how new trucks change a bit. Have been using EDGE products on most of my installs but now will highly recomend the H&S Tuners for sure! Install was on 2010 Dodge Ram
