what plugs are you running? Did you switch to a colder plug? 11-12 af is right where you want it to be for boost. I agree this must be a timing issue, do you know anyone that has some more experience with crome near you? Maybe they can try some things to help the situation. UNCGOLF25 (aim SN) is a friend of mine that tunes Uberdata, crome, pretty much anything. Try telling him your issues and im sure he can help you.
