sct custom tuning question

just trying out my new sct with vivians looney tune and street . love the tune , comming from an h&s product i did notice a nice improvement in shift quality. but my question is guys running custom tunes on the sct do you put the line pressure up in the shifts when loading the tune or just load the tune and be done . also when it says wot shifts whats that mean (on the sct when loading a tune other options) thanks

WOT Shifts is Wide Open Throttle Shifts. As in shift point adjustment for WOT. Line pressures can be changed by the end user if the shifts from the tune writer are to firm or to soft. It all depends on what you like when you drive the truck.

-% reduces shift pressure making the shift softer and +% increases shift pressure making the shift firmer. You have to play with it to see where you like it.

Yes it will...
I always look at Tire revs per mile, and the shift pressures.

Make sure that the revs per mile is CORRECT (you need to search how to find your number) and set it up on the SCT when installing the tune.
For the pressures, I have the same flare when I keep it at 0%... I like it at +10% on every shift except the 3-5. On that one I bump it up to +15%

Keep in mind that your transmission is in a relearn mode
AKA adaptive

try your tune as is for a while /days ,, then eithe ask the tune writer to tweak (best)

or mess with the custom settings ,, and write them down as you play so you can make notes as whet change had what effect

Also, take it easy on the throttle for a few hours after the tune... let it shift into every gear normally before messing around.

I notice that I get the flare when im at around 50% throttle going from 3-5.... Normal driving or WOT driving it acts fine, but at that "median" it's like it doesn't know how to shift.

Ya every time I tune it, I take we easy.. Shifts weird for while and kinda hard, but then it learns pretty good.. And shifts alright.. I bumped my 3-5 line pressure to +25 and it has the slightest flare.. I think I might invest In a solenoid next.. What u guys think?
