Did download without any additional changes yet. Performance has increased. Also sounds better. Very easy to do.

Tuner # 1842 made truck respond like V-8. "Told" tuner that I had different gears to make up for tire size and worked perfectly. It changed dramatically the shift points and acceleration. Love the perf. tune. I think its the best "canned" tune available. 37hp increase on my 3.7 L
