Today I took the car out for a bit and floored it briefly to observe what the fuel pressure was doing under WOT. I'm running Sunoco 94 octane. My boost reached 18 psi and when I hit the recall button on the Scanmaster it showed 2.7 degrees KR which I've seen from time to time so I decided to back off on the boost controller a bit. The boost controller is a Turbonetics manual type. I turned it CCW about 1/4 turn and took the car for a drive again. This time it hit 22 psi and 6.6 degrees KR
...The question I have is by turning the BC CCW I should be decreasing the amount of pressure acting on the top of the wastegate diaphragm, thereby allowing it to open at a lower boost level, correct? I've checked the boost controller installation and boost line connections time and again and the whole setup is only about a month old so what gives??? Is it possible that my turbo is spooling so fast that the boost controller can't keep up with it? As soon as it shot to 22 psi I let up so I don't know for sure if the boost controller would have taken over in another split second or what...I have a second boost controller here (same type but it goes to 25 psi max instead of 50 psi) that I could try but thought I'd pick your brains first...
