i have a blitz DTT and a turbo xs mbc installed and for some reason, the highest reading i get on the blitz DTT on the turbo guage feature is 0.63hkpa, which i think is around 8psi. i adjusted the turbo xs mbc per the instructions, turned it 4 times to try to get 15.5 psi for my boost... i was just wondering how i can tell what my engine is really boosting, or how to even test the max boost (do i just keep my foot on the gas until it readlines???)... and would it be safe if i just adjusted my mbc until i hit the 1.05hkpa or 15.5psi, which is the boost i actually want.... everything seems to work properly.. and when i hit the gas, the boost gauage goes up.. except it just peaks at around 0.6hkpa.. dunno whats wrong.. if anyone knows whats goin on.. please help.. thanks... (oh yeah... it feels like its boosting more than stock.. which makes me think its actually boostin higher than 8psi, also, i also got an exhaust, the apexi n1 installed)... thanks again...

Turn on complete turn for every psi of gain. Set max boost on the freeway in third gear. Hammer the throttle and see what you get for max boost. Adjust and do it again. You will have to adjust slightly for temp or set it at 16 psi on cold day and forget it. It will vary between 14-16 depending on temp.
