just a question about blow off valve set up, how do you balance the valves so that they work equally, the xs type I have fitted are shimmed with washers, but I noticed that when on idle one side piston could be lifted easily compaired to the other side,and of course I noticed a delay between the two as well.I was wondering if the vacuum supply would alter the tension differently, as One side runs off balance bar and the other direct of manifold, I havent tried swapping vac pipes over to see if it makes any difference if you know what I mean, also since fitting these the car runs shit on over run, jerky, but there is no air leaks,and the dump valves are only working after 7 psi. which suggest more washers to remove .??wtf

Balance bar and plenum vac points are the same - there is very little restriction between the bar and the plenum. I'd be checking one of the valves doesn't have a snapped spring etc...

checked spring and its fine even changed for another on still same,

there seem to be less resistance on one side for some reason

 

whats the best way to set up the throotle butterflys, is there a minimum opening setting as I couldn't find it in the worshop manual
