it is still hitting the fuel cutoff at 6300 rpm at 1>2 and sometimes 2>3 and 3>4 regardless of where i set the WOT shift mph and rpm. I read it may be the adaptive characteristics of the TCM just not quite settled in yet. I ran it 5 times but made a few changes after every pass. When I left the track, it shifted perfect on the street.
Anybody have this happen on a 6L80E?

Damn nice baseline...Wish I could of made it, Satuday night drained me...
My 07' Sierra Denali did that a couple times but it would only happen during the 1-2 upshift...This truck has never cut fuel, I did have to up my 1-2 upshift mph some to hold the gear longer when the tires are slipping... What are you commanding in your shifts? (mph & rpm)
If you want compare notes/tunes let me know...

I moved the WOT rpm and mph up and down quite a bit and the only time it didn't do it was the first time I brought wot rpm down from 6100 to 6000 it shifted right at 6000.
upped it to 6100 and it hit fuel cutoff at 6300
