As per title ...could do with one of the uprated (red) springs to go in my Forge Recirc Dump Valve, now the boost is up i notice it opening a little early on lighter throttle which isnt ideal :( .....ive checked and its a blue spring in there at the mo.

Cheers
Ian

Hi Ian, have you thought about shimming the blue spring? Like you i'm having the same problem, i've tried the red spring but get slight stalling of the turbo. Idealy I need a setting half way between the blue spring + 3 shims and the red Spring. If you have a original BOV just compare how much pressure you have to put on the valve to open it. My intention now is to take 3mm off the ledge where the spring sits, so there is not quite so much pressure on the red spring. This also gives me a option to put a couple of shims in if need be.
Cheers Rich

Rich,
I have put 1 shim on the blue spring which was slightly better but still juddery in some cases so still not ideal, maybe my blue spring is tired though... so i contacted Forge and bought one of there Valve Tuning kits, all available springs and a pack of Shims :)....once i get my car back from Waynes i will have a play see what i can come up with, should be able to get something sorted with all the below!

Cheers
Ian
