To do the bov install with the block-off.. I wouldnt have to deal with any vac lines or anything like that would I?

Yah you have to do one vac line then went from the original surge valve to the BOV, pretty easy though, there is one guy on here that lost 5psi after a BOV install and he was able to get it back with the solenoid delete. There is a group buy on the BOV from NeedsWings also, check them out, they are on the vendor list, you'd be number 10 and make it that much cheaper

they have no idea what they are talking about really.. leaving the stock surge valve on while having a BOV installed is the equivalent of having a major boost leak.. My buddy has a nsrt4 that had both the stock surge valve and an aftermarket BOV. With both on he was only holding 8 pounds of boost and peaking at 12ish. after simply removing the surge valve and putting a block of plate on it hes now holding about 13 pounds and peaking around 16-17

I have helped several of his customers out with sending out BOP for the factory surge valve. You MUST remove the factory surge valve if you plan on running an aftermarket BOV. Why they say to keep the OEM unit on there I have no idea, you get zero benefit from leaving it on there.

have to agree, take of the stock one, delete the red wire, cap it, and call it a day. had no problems with boost loss and sounds great.
