Having had problems with spool up and boost pressure with my 008 and yellow spring in i decided to put in my standard Bosch valve and bang spoiling up nice and quick and responsive, does this mean I'm getting boost leak with the yellow spring thus should I try the blue stronger spring in?

Green spring is the shortest then blue and yellow being the tallest, does this seem right

Forge DV springs explained here:

If the car is standard or stage 1, the green spring is usually recommended IIRC.

It's stage one and I understand the ratings but it's strange how it works great with the standard valve and not with the forge and yellow spring it doesn't want to spin up the tubby as if it's not holding boost,

Unless it's to strong but then the blue vents off and boosts not as good as the standard but better than yellow it's driving me nuts

As I understand if a spring is too weak it will cause boost leak

Green spring is fine for standard, & stage 1. Your 008 may need servicing, but try the green spring too.

There's nothing wrong with the OEM DV & in my experience of running several mapped VAG 1.8T's with Compbrake, Forge 007's, Turbosmart & OEM DV's, I wouldn't waste my money on a aftermarket DV again.
