The GrpA has the fuel cut around 17psi and the non GrpA has it around 12psi....varies slightly between cars. Either way you are getting the cut in 3rd (and above no doubt?) as the egine is under greater load which generates more exhaust gas and therefore more boost. It could be your controller just won't allow less boost or you may have a leak in the actuator lines. Either way if you want to run more than 12psi you'll need a boost cut remover of some sort. The CT26 is good for 19psi before it starts running out of Eff but you air/air set up isn't so i'd be inclined to keep it around 12 psi unless you plan some other upgrades. It's definitely not a wastegate flow issue as the twin gates on the 185 CT26 can handle a lot more flow than you are generating before they become a problem. Your exhaust flow has no effect on this wastegate, unlike say the Supra wastegates where extra flow will mean the gates find their boost control limits and you get boost spikes.
