Secondary boost problem (this is killing me!)
I have a problem with my secondary turbo. When I reach 4500rpm the boost go from 0.85 to 0 and then up to 0.4.
I have no ristrictors/pills in the wastegate-hose and precontrol-hose. But the turbos has been working without the pills.
I have recently mapped the car and installed a Power FC.
The vacuum-chamber seems to loose vacuum slowly when trying the chamber with a vacuum-instrument.
Anyone has a idea what the problem could be or what I shall test?
