Default Any reason not to use the big burly blue spring for the Forge DV?

The stock DV hasn't been able to hold the boost much past 18. Looks like green spring is the weenie spring, yellow is a step up and blue is the tough guy. Wanting to hold boost at 24-25 I'm thinking I want to go with the tough guy spring but really don't know much about that stuff. Thoughts?

Default Someone told me not to use that one ....

but only because I dont have a big turbo - you should be ok with it though.

Regardless, I would call ECS tuning and ask, they have always been very helpful to me.

Good luck buddy

Default Well.....you want a smooth transition..>

Between Vacuum and Boost. Too stong a spring delays that and prevents a good dump of pressure because of limited opening. I always found a green spring with 2 shims (or yellow with none) was always more than adequate for 25psi use...More is not always better here..

NP Ken! Always use the lightest spring you can to hold the boost # you need..
