I have a RPM outlet 2.82 upper pulley and LFP #2 lower. I am only seeing 13.5 psi. I have no kinks in my lines and Have used different Autometer gauges. What is wrong? Stiegemeier's chart says 16.0 PSI. Any one got an idea?

no slip and it hits 13.5-14 psi at 4k and holds to 6k RPM
Its because of your headers and no cats. That combo should make about 14 psi. So 13.5 sounds alright
