For those that don't know, or aren't yet familiar with them...GDE (Green Diesel Engineering) is thought of exceptionally well among the RAM/Jeep EcoDiesel owners. I'm a current Jeep EcoDiesel'er with both ECM and Tranny tune...and am spectacularly happy with both.We just got our test F150 powerstroke. It will be several months before we have a validated engine and trans tune. Based on a first drive, the transmission could use revised shift points. The stock performance is not bad, but certainly has more untapped potential.
Have you tried putting it into Sport Drive Mode? I played with that from a stoplight once and I experience a lot more get up and go. I have 3.55 gears in mine. I generally leave mine in Normal Drive Mode unless I put it into Snow/Wet mode.Interested in retuning. I have 3.31 gears which are great for highway but truck is slow at starts.
