E4OD Shifting too high rpm/speed

Ok so I have a 96 f250 7.3L with and auto E4OD and it is not shifting at the correct times. I put 35'' tires on it and changed the psom code to 865 which is the number I got from other forums using the 30282/35=865.2... this was just ballparking it to see if I was close. With that code the truck shifted into second at like 35 mph and about 2300 rpm... In 4 low it shifts at about 30 mph at around 3500 rpm.

I then decided to throw in the lowest code and highest code possible and test drive it. Lowest code was like 400 something and i couldn't even get the truck to shift into second... Highest code was 1100 and with that the truck shifts into second at around 25 mph but still like 2100 rpm...

Ive been looking around for what the shift points actually are, like what speed and how many rpm the trans should shift at. Im pretty sure anything over 2000 is too high rpm to shift.

My speedometer works fine, when i put in the original 865 code I followed my dad's f250 around and the speeds were the same. The transmission shifts fine when it does shift...

If anyone has any input that would be great!

Sounds almost normal. Mine will shift at 1600 if I wait for Christmas. But most of the time it's shifting at 2000+. It's how easy you take it. If you baby it she'll take it easy. Now if I go stand on it mine will start making shifts in the 3500rpm range.
