I'm using a SSR to tune the smoke out of one of my work trucks. It's a 06 with 62/71/14, 90hp injectors, and stock cp3. I played with it yesterday, and the smoke is all but gone. This thing is awesome! EGT's haven't gotten over 1100 deg, but the heaviest trailer I've pulled was 12k lbs. Kinda makes me wish I had a heavily mod'd 5.9 though:lolly:
