My friend has a problem with his setup. Ever since he upgraded to the front mount, he's been having a problem where the car bogs after about 60mph. He spoke with a guy from mach5 and the guy said that he's supposed to have a return line from the bov to the inlet pipe, and since he doesn't have that, the car is running super rich. I'm not sure exactly what bov he's got, but it's an APS unit. Is there supposed to be a line with this bov?
