Shift RPM cant change them!!!

[L2mb]

i can change them in the INTUNE but while driving the shift points did not actually change, i redid the tune 4-5 times raising the rpm from stock 5900? i think all the way up to 6700 and while driving at wot the shift is still at the stock RPM...

this vehicle is a 6 speed so it has the dual tune, i tried changing the RPM in both normal and sport modes, with no difference... i can change the shift firmness and that is actually felt...

Not sure what may be going on BUT is it safe to change the rpm's by 800 and have it wound out like that?

i diddnt change them 800 off the bat, i did it a couple of hundred at a time, not noticing any difference.....

connect the intune to your computer.. go into the inTune usb drive that shows up... go into the TUNES folder... copy the tune files in there to your harddrive.... then attach those files in a post up here...
