    Is your boost gauge right? Looks like you weren't building any boost at all ... just wondering.

    Yup sure is, but I don't know why it doesn't build any boost revving in neutral... mabe because full exhaust out the back?

    The engine needs to be under load to build boost. Revving it in neutral doesn't cause much of a load
