Happy New Year!! I am finally getting my svo on the road. Should I leave the boost gauge alone, or should I get a gauge like I see other people having? If I get a boost gauge I was going to mount it in one of those pillar mounted gauge pods. the ones I have seen are usually 2 or 3 holes. What would be the best gauge to fill the second hole with? Also what is the diff between a mechanical and electrical gauge? thanks
