forge bpv

[aliencx7]

Hello I do not own a speed6 but my dad does and he bought a forge bpv. What spring should he use on it?

The yellow one. It should already be in the unit.

I'm using the blue for my CX-7, but swapped it last week on my MS6 and works great. I've read somewhere that the yellow was made for other cars the have 1.8T. So, they've said that Forge should be shipping to MS6 owners with blue springs.

Feedback I've been getting points to the blue being the best choice for stock or mildly modified cars.

I switched to blue springs too...seems to be fine. Was using yellow with 1 shim before...
I swapped cause I was curious but it's works great either way

I called Forge when I got the valve cause it didn't mention anywhere which spring is for what. Their customer service told me the Yellow is for 15-23 psi, Blue 23-30, and Red 30+. Just have to watch your boost gauge (if you have one) to see how its handling the boost whether its letting it go to early or not letting enough of it go.
