First of how fast? Flat ground? Was the wind blowing in your face? How long since turbo has been cleaned? Mine always ran about 5 PSI @ 70 on flat ground with no wind. I took my turbo out and cleaned it, discovered that I had 3 veins that where sticky and had restricted movement. Now on flat ground, no wind, 70 MPH I run about 3 PSI.
