    Opinion on which guages (A/F, BOOST, ETC)

    I was looking at getting something like this:

    Perrin Performance - >Gauge Pack Combo Boost/AFR

    But was kind of unsure as to what would be most beneficial to have besides the boost gauge. I'm high altitude, CO, if that makes a difference. Future mods will just be simple until warranty is up, prob. just cat back exhaust and call it good for now. I'm more concerned with just keeping track of my car and making sure everything's good to go. Thoughts?

    Also, if anyone has a better idea for set up in an 09 I'm all ears. I figured this would be good to keep the gauges visible but out of the way. A-pillar is out b/c of side airbags and I don't want to mess with my radio and do a custom set up. Thanks in advance!

    hmm the only one I would recommend is an oil pressure gauge.

    IMHO, go with boost/Vac, oil pressure, egt and maybe a wideband A/F. In that order too. Happy modding.

    I wouldn't run WBO2 on a stock car - it's a waste. You'll need to tap the OEM downpipe before the first catalytic converter, which some people would say is too close to the turbo and can lead to premature sensor failure (and at $75+/each, it can get expensive)

    Why Subaru didn't include an oil pressure gauge on the cluster is a mystery to me.

    My vote (if you're going with two gauges):
    Oil Pressure

    Also, make sure you read reviews on the quality of the products; a few really good gauge manufacturers are Defi, Greddy, and Omori. They may be a little more expensive up front, but an inaccurate gauge is worse than no gauge at all.

    great link....thanks! I guess generally opinion is boost and oil pressure. Now to go through the joys of picking a gauge and mounting (still not sold on the perrin unit..something about universal fitment makes me think it'd look crappy)

    i went with Boost, Oil pressure and Oil Temp... the two oil gauges were easiest to do together becuase the adapter leaves spaces for two sensors...figured i should just use both spaces...really helpful i plan on getting an exhaust temp in the spring though
