I too am now taking the off-road only plunge with my '13 NMS since I decided to keep it. I am dumping some unexpected new found funds into the car, nothing coming out of savings so what the heck.
I ordered everything today. I ordered the Garrett CR190 turbo kit with just a straight pipe, the down pipe/dpf delete, and a Malone stage 3.65 tune upgrade. I could not find anyone else with this setup yet to help in making the decision to go this route so I guess I am taking one for the team. wish me luck!
I also ordered a big brake kit, new Bilstein suspension, and a kick ass sound system that will blow my hair back. It was either all that or wait for the new cheaper Tesla that is supposed to be ready to buy in a couple years. I just really want a car I do not have to fuel up once a week.
I currently have a Malone stage II with the DSG tune, an aFe cat back, and aFe intake. Honestly I could not really tell much of a difference from stock, if any, in the lower gears other then it does not sign off as early. 4th-5th seem a little taller, a little nicer. I do feel a little bit more torque on long steep climbs. I honestly feel the DSG tune did more for the car then the stage II, buts that's just me.
That said. I will do my best to articulate my impressions of the new config once I get it up and going and to gather as much real data as possible.
Here is the kit, I am sure you all have seen it by now
