Well yes but it still seems really low for 10 Psi. I hit 175 with standard boost, std cooler, pod and cat back. I wouldn't up the boost till you at least get a Hi-flow cat and perhaps a dump or split dump pipe. Seal up your plugs to be sure and you should be able to get close to 9Psi without even touching the boost controller.
Your plugs at 0.8 should be fine. Whilst .7 or .6 may seem to fix a problem, it usually only "covers it up". Find the cause of the issues rather than trying to cover them up methinks.
