Hi..Is anybody running this valve..I fitted mine and it would not stop screechin..
The spring seems like its got no resistance wot so ever..Im running around 1.4 to 1.55 bar and its come fitted with a blue spring...seems far to weak but on there site it says 23 to 30 psi handling...

 

Ring Forge mate, they are very good and will advise you, it has been known for them to supply the correct spring FOC

 

They do a service kit, several springs/spacers to adjust the operation, I needed a change on fitting a front mount.

Cheers Mate..one on the way..came to about 19 and a half punds..
Plus got to add the car throttle response really sharpened up with the Forge valve on A-road runs..it was just when ya got on the motorway and put the foot to the floor it was like a whistle plus the fact the boost would build up then just pi$$ off..
