Title: Disappointing
Review: I purchased this product with high hopes that it would deliver as promised but alas I was severely disappointed. Both the Regular and Premium tunes caused my truck to have very poor performance over stock. The shift point and firmness settings made absolutely no difference whatsoever. The odometer correction for gears, tire sizes, top speed limiter and rev limiter are the only settings which functioned properly. I do like the drag strip, dyno, and gauge functions but not enough to pay a premium price. Deal or Dud you ask? Definitely a DUD!
