So I was driving today and felt the need to pass the driver ahead of me.... in doing so I hit full boost... or wait... I only hit 10 psi on my 15g greddy turbo... My MBC and tune was set at 15lbs since last summer... how come all of a sudden it doesnt go past 10?! It sticks right on and doesnt move.... I checked the charge piping... everything was okay... check the bov.... it was okay.... is there a pin hole in my vaccuum maybe? What else could it be?!
