    Hey.......


    okay, straight to the point....... 1st ptoblem, when im driving normally i take my foot off the pedal and the car feels like some has just drove up my A$se! Like a shunt. Does it all the time(except for the first 5 minutes from cold) any ideas??


    2nd problem, sometimes my boost drops, mostly to 0.3/0.4 bar (currently running 1.1 from a re-map) it does under NO specific load, sometimes if i floor it, sometimes i can be just driving under load (apx .8 bar) then all of a suddeni can hear the bovs dump and it will drop to 0 and get the shunt back, as if i took my foot off the pedal.

    any help would be great

    Try posting in the B5 forum, think it was the same engine used in the S4.
