i think my plumb back, blitz bov was also bypassing at high boost so i have replaced it with another one
i had laying around, and i was able to drop the ebc duty cycle down 15 % and still make the same boost.
may have had something to do with it.
im heading back to the dyno in about an hour so i will try again with the new bov and see if it levels the boost out a bit.
1.5 bar ya reckon Gary..
that will get my missus to the shops in a real hurry...
