I really want to add a boost gauge as well. I've seen Stratton's (and a few other user's) ultragauge setup and while I think it is super cool and clean looking and much easier to install, I really want a gauge. In my opinion, I really like gauges over digital. However, I'm kind of new to this and I don't know which hose to tap into to get the boost pressure. I've looked online and have found stuff on other turbo cars, but the Sonic looks different.
Any pointers would be greatly appreciated. =]
