Default Forge DVR - how to select a spring ?
My Forge DVR came with few springs of different strengths. What are the considerations of selecting a spring ?

MY car is a stock 2002 225 TTQC.

Thanks,

Tal

Default I tried the blue and yellow one today. Ended up staying with the green.
The valve was making some odd sounds with the stiffer springs. Almost like a skipping pssst sound. How many springs came with yours? the sheet said 2 extra but I have 3 extra. yellow, blue, red, and green which was installed.

Default I'm actually using Yellow. Green did not respond as well. Felt like I was losing boost.
I have an APR chip though.

What is the affect of having a softer or harder spring ?

Default Determines...>
How easily the valve opens when vacum is applied to the control line, and how much boost it will hold under extreme condidtions..
