So I got the superchips in today.
Loading it onto the truck was interesting. Does some strange things while tuning. turns power on and off to everything in the cab. Toward the end of the tune it turned the head lights on, then the heat, then radio. Had a big wtf moment for a minute.
Aside from that. Loaded the performance tune. There is a torque management on/off option which I really liked. Theres three options for trans shifting 1,2,3. Not sure the difference but I went with (1). It shifts like stock just quicker, no delay. Not hard or hunting for gears. Power was extremely smooth. Throttle feel was nice and smooth. Much more responsive, like a lot... While I only got on it a few times, power was much more then I was expecting. It maybe the 480whp that I hear, But I am guessing the torque is higher then a comparable hp 6.4. It feels very comparable to my 6.4 on the spartan 210. Only much more smooth and quiet. Its cold out (5 degrees maybe) But there is no traction at all. Don't bother even getting on the throttle till 3rd gear. Can't comment on fuel mileage till I get some normal driving in. So far extremely happy.
