Yes another DV question.

What spring rate / colour are you using or recommend for my car. The car is getting another remap soon, im hoping for around 1.2 / 1.3 bar or more if possible.

Cheers Phil. /slippy

...Based on their example then the lowest GREEN should suffice, but I'd fit a YELLOW one if you intend to go for more than 1.2+ bar (17.4+ psi).

Have a look on the forge web site, they give you all the spring colours and there ratings as you can buy them direct. i run a blue spring on 1.3 bar.

I've used the Forge VTA on my car and to be honest anything over 1.35bar the blue spring cannot handle it. I ended up replacing the small spring,pistons and large blue srping with a added shim. It still didn't like it.

So I ended up going for a RED spring.

I now use the Forge recirc DV. But with a RED and added shim as I am hitting 1.55bar.

I think the colours even on the Forge website are guidelines.

At the moment ive been using the blue spring. Ive been noticing when I boot the engine the dv dumps with no problem and there is a slight turbo chatter. When im easy on the turbo there is no there is no noise from the dv, it sounds like a faint blowing noise from somewhere.

Just off the phone, Forge recommend staying with the blue spring with no shims fitted.

Check the smaller spring also. They are weaker than the larger BLUE spring matey.
