Stealth Module - Ford Powerstroke 7.3L (1999-2003)

2001 F350 7.3 Stock w/ 1.3 million total miles

I installed the Stealth System in about 10 minutes, very easy! I pulled a 27ft. Travel Trailer 175 miles from West Richland, WA to Spokane, WA via 395 which has some small pulls and flat land. I was most impressed with the fact that the transmission DID NOT kick down on the pulls yet held speed. I averaged 16 mpg up and back on 1 tank of fuel. A month earlier I pulled a small car up to Spokane on a tow dolly and the Transmission kicked down twice and lost speed twice on the longer pulls. I was very impressed with the Stealth System, now I will be installing my pillar gauges to keep up with the EGTs, Transmission Temperature as I am concerned as what are they doing with the activity of the Stealth on the Fuel system. Yes I have an over size Transmission cooler, but what about EGTS? I will find out. My initial thoughts are the Stealth is doing what it is supposed to and what they advertised! If the EGTs stay in the ballpark of where they are supposed to I will be Extremely Happy!
