I believe that changing the primary bov is not too hard. The secondary is another story as this bov also controls the spool up of the secondary before the switch over.Why the need for atmospheric? Advice i have seen on the twin turbo web site is that the std plastic bov on the primary is utter crap and is a common cause for fluctuating boost levels. So replacement is a good option. Also to be noted is that atmospheric bov's dont seem to lead to overfueling on TT's.

You should only have to do the one on the primary. the one on the 2ndry is mostly for looks
