Highly modified CTS-V 3-4 shift

I have a ctsv that makes around 840hp boost only and 1050 or so on nitrous.   The tune is scaled bc of the injectors and has a 5 inch intake on it.   I have messed with the Virtual trq to get the trq readings correct but if shifts hard in the 2.3 shift and 3.4 shift will shift but takes too long and flares before it shifts.   Car has a 28 inch tall tire on it.
