2 bar overboost, immediately stabilized at 1.8 for the reliability.

I checked the pressure with VAG-COM, they are OK.
I publish the report soon to of bench.
I run a similar spec (same turbo, with headwork injectors and cam) and mine peaks at 2bar and is making similar power to that
It should not be confused with a stock turbo with a turbo that has a larger turbine.
