Ive been gauge shopping and dont have a clue what to buy.I know that a boost gauge is a must have, and a egt gauge is a must have. I do have a lm-1 wideband but i didnt get the xtd gauge with it.I wasnt sure if it was a "must have" or not. I would like know if im going in the right direction, and if anybody has a specific brands please suggest them.
