Killer setup, I thought I was the only one to do a new garrett TS! Morrison absolutely killed it on your setup! I have a G35-900 TS also on an IX RS. With S2 cams and essentially stock long block I am seeing 20psi in 4th gear around 4000-4100 rpm. I have the Gen 1 so I would not have a ceiling quite as high as yours but it makes for a very fun street setup. I still have yet to turn mine up but it made 620 dynojet on 93 with some 110 sprinkled in for S&G on 30psi with very conservative timing. I dont mean to hijack but this is what mine looks like with stock size rad and AC!
