2 Blow-Off Valves?

[stu02_m35]

Hi Guys, just wondering if I can run the factory blow-off valve and a full venting blow-off valve inline together?

Would I lose too much pressure or will the factory

Valve pretty much vent nothing back into the system?

Cheers

Why would you want to?

The Turbosmart Dual Port I have on mine is supposed to be able to be set up so that it recirculates below 17PSI, and vents to atmo above 17PSI.

Pretty sure your AFM would have a shitfit if you set it up like that, unless you we're running a MAP sensor instead.
