1.) Are there any advantages in getting an aftermarket BOV over doing the $0.16 mod on the stock BOV?
The only reason I'm considering an aftermarket is that the moded stock surges somewhere between 5-10psi.
Will the aftermarket recirc valves do this as well?
2.) What is the difference between an adjustable BOV and a 2 stage SSQV?
I'm just looking for something that will hold 25psi of boost and not cause any surges.
