    Boost control

    Slight issue with the S6, it'll drive off and moderate boost, cruising, and at pace fine, if you put your foot down in 1st you usually get full boost, but in other gears it'll spool and shoot up to 2 bar on the digi gauge, then come 3.5k it'll drop to 1.4-1.6, jump to 2 again at 4k for 500 rpm, drop, and come back on 2bar for 5.5-7k.

    I've changed the n75 valve, and jubilees in that area, will going to replace the entire vacuum system with silicone and new clips. After that what else could be the issue?
