So after having sat for a couple weeks, I got my car out and had the new drag radials put on it. Im testing the new boost settings, and I'm only able to get 33psi out of it. 2 weeks ago I could get 36psi. Boost controller is set to 100 (max) the vacuum is at -17 and sometimes goes to -18. I tried a boost leak test but my pcv vents to atmosphere so all i hear is air coming out of the drivers side filter. could this be a boost leak or something else? Any ideas?
