I'm on nasioc, and while I don't post much, I learned a lot about the ej's tuning potential. That combined with a friend who was willing to let his car be my guinea pig taught me a lot about subie tuning. I'll have to check out the off topic, it should be really interesting.And they exacerbate every pro it has, too. Car forums.. A breed unto themselves.
The boost guage in my '11 WRX started flickering yesterday, I looked it up and found the answer on nasioc, (they're still good for that sortve thing). I had no idea the off topic section of nasioc was one of the biggest off topic forums on the net! How these people ended up converging on a subaru forum is beyond me.
