Message	I was running in some very cold air tonight and noticed some strange behavior. My Autometer boost gauge was showing close to 20 PSI in 3rd gear and my peak hold function on my AVC-R showed 1.36 BAR or just about 20 PSI. From what I know I have stock turbos and injectors and I never ran out of duty cycle or even too close according to the AVC-R. Also My tachometer was showing rev up to about 7600 before I was shifting in 2nd and 3rd. I shifted before fuel cut. Now I know these numbers are off since I just had the car dynoed at Z Fest here in Orlando this last weekend. AVC-R has two settings, one is set to .60 BAR and the other is 1.0 BAR. I figured either was safe on my stock turbos, injectors and motor. However the AVC-R still showed these huge values. Scramble boost is set to +0.0 so that should not be a factor. When I had the car dynoed, the setting was 1.0 BAR and resulted in the graphs below. AFR seems fine too. I was not in the car, so I don't know what the revs and gauges showed. What could cause the numbers to be this far off?
