Conor , Forge don’t make that model anymore but I’m confident they have the service kit ,
Fire an email over with a couple of photos and the year of your car and they should be able to help

Very helpful lads in there , have always looked after me

Whats up with it ?
Most of the time it’s just a couple of o rings a clean and put back together .
If your running more boost than factory you can get a heavier spring

Think the spring is fucked in it. Sounds like its stuck open, causing car to splutter and fart 🙈
 
Conor what colour spring is it there diff colours for diff boost levels bought kit few years back not sure if still have it but will look for you if suits.

Looks same model as I had or was mine more dished..

Serviceable too mabay just needs greese🤔

The vacuum at idle will open the valve which is normal ,
it closes when closer to 0 vacuum and on boost and then when you release the throttle opens again

Cars with airflow meters needs a recirculating type valve to keep the readings correct

Stripping the valve cleaning it and putting a small bit of red rubber grease on the o rings may help if it

Didnt open it up yet to see colour.
Think urs is more dished
 
Chances are the piston and service kit are the same as yours Con ,
Email them to confirm,
if you want a hand doing it , I could do it at a meet for you but I’d advise getting a new intercooler to dump valve gasket
 
Dad got back there not in folks and not here apologies

Typical tripping over em for years must have went into bin.
