I thought blow off valves don work on engines with a MAF air metering sensor?
They certainly can work on a MAF or MAP based car. Normally on a MAF based engines, you need to recirculate the blow off valve vent back into the intake of the turbo to prevent blowing out “metered air” and having the engine run temporarily rich for a second. With the Jattus Performance turbo kits, the MAF sensor is placed in the charge pipes, completely illiminating the need to do that, and keeps the blow off valve nice and loud.
