Ive seen conflicting spring colors. Im getting mine soon and was curious which color to use.

Its on stock pulley at 7.5 lbs.

Anyone have a definitive answer which spring should be used with which psi?

 

I think maybe why nobody has answered your question is because it's a bit conflicting.....you mention a stock "pulley" which makes me think supercharger but you also are mentioning spring color which leads me to believe you're talking about a wastegate spring. Please clarify and I think we can be of assistance.

 

The forge 007 in the title of the post is a diverter valve.

So yes. I have a supercharger. But the oem dv is garbage, so I'm replacing it with a forge 007 dv which has springs in it.

I found my answer on the Forge website.

It's green for 5-15 psi
