6.5-7psi is normal for the 7psi pulley, i happen to make a solid 8psi due to a slightly smaller pulley being sent out...... this can work either way..... i got lucky :-)

6.5psi will get you the vt2 experience, some checks/movement on clamps/hoses will no doubt get you your missing 0.5psi :-) your nearly their iphone..... your nearly ther bro!!!


FYI the bpv have an adjustment nut in the middle that comes pre adjusted from vortech...... tweaks alter its behaviour :-) imo id like to get an "aftermarket BPV" with part recirc part vent to atmosphere capability, i believe the ess flange design is a popular fitment type.....
