HELP, rookie needs help

[COFF]

Ok, have a 2001 F350 7.3L sw SD. have a beautiful purple ATS trans, that kicks like a mule 4in pipe, and some chip that i cant find.

here is the situation or multiple of situations. runing 38in tires with 456 gears on the highway at 65-70 ish i am runing at 2300-2400 rpm and 3-6 on boost.. where should i be for this speed? next my oil temp says that im at around 230-260 max when i run for about an hour or more? is that too hot? all my other temps, pyro, and colant are in normal ranges. no one can give me an good temp i should be running and if i am in the norm.

so back to the trans, if i step on it, it shifts like a porche ( not that i know what thats like, but i would imagine smooth). if i baby her and go easy, she kicks in a 3rd and od. is this normal?

last but not least.. what do i want to run for a programer once i iron out these isues?

I know a lot of questions, but any help would be nice!

Thanks and God Bless,
j.d.
