PS i realy hope im right

yeah you are right in a way mate, a std rs turbo ecu wont boost above 10psi unless it is chipped, the boost limiter will be hit anything above 10psi and the revs will drop to zero.. if u want to run 14psi u will need the ecu chipped,,
unless u run a bleed valve but i advise u NOT to do this as mixture and fuelling will fuck up along with you engine..
