42RLE shift schedule tuning

hi all

i want to tune a heavily modified 2005 Jeep 4.0 (stroked to 4.7, cnc head, cam, intake, headers, etc..) to shift later for better use of the powerband.

so, regardless what i write in the shift schedule, it shifts at 4600 under WOT ( i write 8000 in it for testing purpose)

any ideas what i can do here?

regards

Reini
