Also, to disable the boost cut just pull the hose off the bottom of the boost pressure sensor (next to the grey box labelled diagnostic) and plug the hose up leaving the sensor open to the air

So wat do they boost as standard ???

Standard they are t/vsv controlled from 7->11.8psi

usually you should run 10-11ish

optimal conditions (up to temp, good quality fuel and cold intake air) will net max boost of 11.8

Ok noob questions;D

whats t/vsv???

turbo - variable solenoid valve

under optimal conditions it opens and bleeds air away from the actuator, so the turbo has to work harder to fix this 'leak' so it raises boost 3-4psi or so

its a factory boost controller
