So I've purchased a 2 gauge pod for my '11 WRX and am looking to fill them. I've already purchased a boost gauge that matches my instrument cluster and it was suggested to me by my tuner that an EGT or WBO2 and AFR are what I should be looking for as a second to be able to keep track of how my car is running. So I have a 2 part question... which do you all think would be the most important 2nd gauge and do you know where I can get one that matches (Red face with white needle)? I've looked for hours and have found very few with that color combination. Thanks in advance!!
