Hi, I have a 1752v hybrid turbo on a vrs asz and it is overboosting to around 45 psi, obviously I dont want it to go bang so im looking for some advice, I have switched to an n75 mod to try and fix the issue as the map was for the n75, still nothing has changed, i’ve cleaned my map sensor and checked for leaks, I can hear a little hiss but nothing major, turbo hasn’t even done 20k miles, nothing else feels unusual other than it just boosting way above the limit and it gets thrown into limp mode, any advice, many thanks.

Actuator stop screw may have come undone and no longer be limiting boost.
