Yea Spartan has a tune called "The Warhammer" that gives you 200hp.. They are about to release some new tuning for the newer trucks. But say they are looking at some revisions to older tuning that could lead to even more power
I have 70k on my 13 and the only time I have heard the tick was when I used 15w40 one time... The rest of the time I use Delo full synthetic or Motorcraft 10w30
