they bleed off pressure between your manifold and map sensor so the map doesn't see your boosting thats what they do

as i explained further up

"they bleed off pressure between your manifold and map sensor so the map doesn't see your boosting thats what they do" NIK

go look under your hood see the map sensor and the vac tubing coming out of the bottom and going to the intake manifold ..... now see the pic i posted you pull off your tubing and connect the check valve system and your done dude you should know n/a map sensors dont like boost so this is how you fool them or you can hardwire in a 1 or 2 bar map sensor but you have to make sure the ecu can under stand it go out a buy ..... i can remeber the of that boosting book anyways go read up it will probably answer some of your questions you keep asking
