Matt and Jeff its great to see both of you on the forum and staying interactive with the people on here and asking for and accepting input. This thread is my sole reason for spending the extra money and going with Spartan Tuning on my 15. I have heard bad things and good things about your tuning on previous year trucks, mainly high horsepower(good) and hurting transmissions(bad) but after reading everything Matt has said about the trans, the tunes and his overall knowledge about these trucks it has made me believe in both of you and the company as well. I think ya'll are definitely on the right track as far as tuning, options, SOTF and most importantly customer service. Knowing that I can count on the seller to back their products and work out any issues is the number one reason to purchase a tuner from Spartan. As far as the switch goes I am very interested to see it, but my first instinct is to have it hidden (this is how I did the switch in my 08 DMax w/ EFILive) and to have at least 4 positions. Tow, DD, Fun, and Max Performance. I'm thinking a temporary hidden mount in the storage slot on the drivers side of the console would be the way to go. Either that or intergrate it into the dash mount that will hold the nDash. Also do you have more info available on the new nDash as far as pictures, mounting options and the screen layout? I would also be interested in seeing you test your tuning with the 5" open intake from No Limit Fab or Absolute Performance as sometimes these throw codes with custom tuning where other intakes did not and I would also like to see if there is any power/performance difference. Thanks again for all your hard work and still finding time to get on here and share your testing experience and knowledge.
