After transmission relearn procedure I can’t get about 60 mph

What’s up guys.. I just deleted my 2017 f250 and after I deleted it I found out it’s common to have to do a relearn procedure on the transmission due to poor shifting habits with the tune because these transmissions are super delicate. Well I uploaded the OEM No Emissions Calibration file onto the truck as requested and then loaded the KAM Reset Beta V1 file and then returned the truck back to stock. Once all that I began with the procedure they sent me. I took the truck out onto the highway to do all the driving they requested and the truck would barely make it up to 60-65 mph. I finally got though all the driving portion of the procedure and the truck shifts better now and pulls through the gears better but 60-65 is about top speed. Has anyone ever ran into this issue? Last time I did the relearn procedure I uploaded a tune and with it it’ll drive normal but with the truck on stock it does this. A little more info on the truck it has PPEI tunes and is sitting on 6” lift and 37s.

Get good tuning before you ruin your truck.
