[QUOTE="Cannonfodder, post: 2037497, member: 23265"] EVOs use a MAF, which meters air into the intake loop prior to the throttle body, what goes in, stays in as far as the ECU is concerned. This is why the EVO uses a recirculating valve, that is you already HAVE a blow-off valve, just that it doesn't do an atmospheric dump to make that 2F2F sound so many people expect from a turbocharged car. If you install an atmospheric BOV, what you do is allow air that the system thinks is still in the system to escape, which means that when you shift, you run rich. You may also stall if you jump quickly from the accelerator to the clutch, for example in slow traffic or at intersections. Some people experience relatively few problems, some people experience more, so your mileage may vary if you decide to install an atmo BOV as long as you maintain the MAF setup. The only real way to make sure no problems will exist is if you have either a blow-through or MAP intake metering system. Otherwise, make sure you don't throw away your original valve ;) [/QUOTE]
