Bry, I fitted a boost gauge and compared the DV10 and the Standard DV and my findings are, with the standard DV peek boost pressure is 13psi 0.9bar and with the DV10 it drops to a peek as low as 10psi 0.69 and is all over the place under load. So like Cal said you will probably need to tension up the spring so it doesn't leak or lift of too early.
