Help w/ strange TC/Shift issue with Fuel Sipper tune

[soutthpaw]

We are thinking along the same lines.. I am wondering if the altitude is an issue as I am at 6000ft

I changed the tire size based off the BFG chart for my larger tires 315/85r16 maybe ill change it back to the stock 653 on one position and see if that changes anything... if it does then Ill try changing the shift points by the same 8.7%
I was thinking about the torque but shouldn't be an issue at light throttle right?

How does the rpm for anticipated and non-anticipated shifts work? Like I said in another post I am not well versed in transmissions.. I did not have a chance to go run the AE today... I think if i can identify the exact rpm and throttle position TCC status, MPH it will help a lot in fixing it... its basically Bills stock FS file... so its weird that it only seems to do it in that setting though I know he said that the shift points are lowered compared to most of the other tunes... that is why I was thinking its a shift point issue...

I gotta do the front axle and brake overhaul tmw. so not sure if Ill get to play with it... depends on how much time the other stuff takes.
