[QUOTE="unit213, post: 7038769, member: 8896"] Personally, I have no experience with a 2.6L KB so I'll have to defer to KB's website for info: [IMG]http://i35.tinypic.com/hwy9o5.jpg[/IMG] It looks like the 3.25 upper should make 20psi. That's around 24psi with your 4lb lower. Do you have long tubes by chance? You're missing around 5lbs of boost and having headers certainly isn't going to decrease boost pressure by 5psi...maybe 2psi at the most. Just snooping around though. Have you ruled out belt slip yet? Do you have a current dyno graph to post? Can you post a few pics of your engine bay, specifically your pulley setup? A picture is worth a thousand words... You also didn't answer my question about your Metco lower pulley. Are you sure that it's properly aligned and that it's not out of balance? Another question...how do you know you're only making 19psi? Do you have an autometer gauge? Are you using the stock gauge? Etc, etc, etc. [/QUOTE]
