Upgrade your Evo Upgrade your Edge Evolution to a Gryphon Programmer to allow for custom tuning and additional functionality. Due to issues with the cable failures due to incompatible versions of firmware, we do not offer upgrades or tuning for the 1997-2003 F-Series gas or 7.3L diesel trucks. We recommend using another platform. |

If I do that I think my RPM is just hitting 3k at that speed with the TC locked...I have 30 inch tires with 3.55 gears. I'm going by math and what I usually see cruising around 70 in 4th, funny I was pulling up a grade with over a half ton in stuff earlier and I didn't remember what rpm I saw at the 60ish speeds. Wish I had read the post sooner. Edit: pulled some info from some data logs and made some estimates. I'd be running around 3100 rpm in 3rd with the TC locked, so my memory isn't too bad. With 3.73 gears at 35s you should be sitting even lower than I am. Now if the truck already had 4.10 gears you would be just a bit higher than me. Are you 100% sure the truck has stock gears? What axle code do you have in your door jamb?

Yes I do take the O/D off been doing that for years when towing. Old habits die hard and I learned before I was even driving when towing don't use the O/D.
I'm pretty sure they are the 3.73 gears, from what the paperwork states and when I first hooked up the evo that's what the ecu says it has in it. I'll check the door jam later to make sure.
