Right heres ny prob ; i'm building an erst and just got my metering unit today and was planning to fit it but then i noticed that it has two outlets next to where the boost hose connect and i dont have a clue what they are for. this is my first time working on an erst. so some help would be brilliant.

Cheers Kev

 

 

Anyone? c'mon am dying to get it going.

 

Breather system is large one, amal valve return is smaller one.

 

Hot the fcuk is an amal valve? can you run without it?

 

it will run i think but it controls boost level so be carefull

 

or put bleed valve on be careful if u go for dash mount get boost gauge or u weel melt pistons
