I have had the engine (Powerstroke) tuned to the "A" program for a little over a week. There is a definite power increase at higher rev's (over 2100 rpm, approximately). I am in the process of checking fuel economy. If I can pick up 2 or 3 miles to the gallon with the increased power and torque, I'll be one happy camper. I was getting 10.5 mph towing a 10,500 lb fiver and about 14 mpg solo. My truck is a crew cab dually, four wheel drive which I've had for 6 years. I will post my results in a couple of weeks with the info. So far, it looks good.
