    When in 3rd did you do the pull from ~2500rpm up to redline?

    I've just checked a log i did of mine (which as far as i know is stock) last October and I managed a peak of 169g/s at ~6300rpm

    So you may have a boost leak somewhere. Next step would be to check the boost requested vs boost actual.

    The measuring blocks I use to log boost pressure are, 002/115/118

    My mpg is averaging at 23mpg, that's me working it out, this is driving on decent roads without hard acceleration or braking, I would expect high 20's, anyone got standard maf readings or can tell me if mine is any good that would be appreciated
