Yeah, running my OEM ECU until I get it professionally tuned. Don't have any idea how to tune it, so I don't want to risk messing something up royally. I have the series 1, didn't even know anything about the series 2 until you said something. I was going to be upset for a second until I looked at AEM's site and read some details about it. Doesn't look like the one for our cars is out yet, and the new one doesnt appear to add any new features worth spending the extra money for. I purchased it from aemonly.com several months ago, so it will be nice to finally get it installed and tuned.
