What springs are you running? Is there any belt dust on the pulleys? Have you hooked up a different boost/vac gauge at all to see if its your guage? 3psi is sure a big diff. from a cam like that.

edit: yes cam installed straight up with 4 degree advance ground in.

Given it the good look over. No evidence of belt slip. No evidence of balancer pulley turning. I am confident the boost gauge is correct. Truck runs great, solid steady instant boost to 6 maybe 6.5 at shift. No studders, no surges, good steady pull. I lost 2 to 3 psi boost when I installed the cam. I guess installing the new pulley will be the true test. Wish I had it tonight. The air is great
