So i am having some serious issues trying to get my car to run right with a bov installed. I am running a custom blow through setup really similiar to the greddy kits. I am using a 56mm open vent valve and it is causing a disturbance to the MAF signal. I have moved it from up close by the maf to down in my bumper cap. It is prolly 2 and half feet and two bends away from the maf. The spring I am using may be a lil soft. It is fully open at idle vacuum but i still didnt think it would cause that much of a disturbance. The valve is a JGS 560 o-ringed piston style valve.

Any thoughts I have been beating my head against the wall trying to get this thing running right...

shoulda done the LS swap lol

 

anyone?

 

what kit are you running? custom? supply pics. 56mm is a big bov.

 

MAF and atmospheric = no no simple as that.
