Re: Boost of 2.0 Tb
I believe if you do not control the wastegate at all (that's what the pierburg/solenoid valve does) the turbo's pressure will remain at 0.5bar.
Standard, during overboost the turbo should be able to push the pressure up to 1.1bar I believe.
I've just let my car be 'chipped' by Squadra Tuning, so now I have 1,5bar during overboost, but during the install the guy checks for errors that might be there. I had 'detonation sensor no.1' giving an intermittend signal, so the ECU went into the emergency-mode and then you'll get a turbo pressure of maximally 0.5bar. But the V6 can handle 1,5 bar, so keep that as a maximum pressure.
As you do see pressures higher than 0.5bar (is your gauge accurate enough?) is seems you don't get the overboost. How old (km's) is your turbo? And what you might also check is the tubing that runs from turbo to pierburg/solenoid valve, they can be leak and also knick sometimes influencing your turbo's performance.
