How tense should I have my spring? From what I understand, the bigger the turbo, the stiffer the spring needs to be. I followed the instructions that came with the BOV, but the range is quite large before you start seeing low idle's and backfiring.
Does the spring control how much air is expelled, and how much goes back to turbo? For example, the tighter the spring, the more gets vented to turbo, and the softer the spring the more gets vented to atmosphere?
Any help would be appreciated!
