SIlly question, i no they have a guideline on the site! Iv got a Forge DV and an MRC remap. Its at about 0.8bar ish. Now do i stick to the standard spring (Weakest) OR move up to the next one. I can hear the car dump each time i let off. And it seems to hold boost. Would putting a harder spring in give it a little more peak boost? Thanks all, and again sorry for the silly question!!
