Hello folks,

Question about boost at elevation. Right now I'm in Wyoming and about 6300ft of elevation. The DA is anywhere from 8000-10000ft at times. I have a stock upper (2.50) and a lower 9.60" pulley. Also have a cam with 3.5* over lap and 2" headers. At sea level the car was seeing about 11-12 PSI. On my logs here I'm seeing about 5-6 PSI. I don't have any vacuum leaks. Could elevation and DA play that big of a role in how much boost I'm making?
