I added a 6-position tuner from Xtreme Diesel Performance to my 1995 Ford F250 that has a 7.3L PowerStroke diesel engine in it.
PowerStrokes came out in 1995, and mine is an early build with a Sept 1994 build date. From the factory, these first-year trucks were VERY under-tuned, even compared to just a couple of years later. I have had this truck since 2011, it had 70,000 miles on it then, just went over 150,000 recently. These days, it is relegated to pulling our 34' Avion travel trailer, or for whatever I need a truck for..... no more daily driver.
The tuner's 6 positions are: 1 = "stock", 2 = high idle, 3 = +50 hp, 4 = +75 hp, 5 = +100 hp, and 6 = +150 hp.
I took it for a spin after installing, and the improvement is very noticeable in each of the "+" positions..... it's like the truck woke up! I am looking forward to our next outing with the trailer..... heading to Red Rock Canyon park in Hinton, OK...... about 275 miles from here, with lots of really good hills to go through just south of here on our way toward I-40. Curious to see how it feels with this tuner! Should be very evident.
