Aem Ems ???
Do a search on the AEM, as there's been some discussion of this topic already, although mostly in the context of fuel management for turbo owners. I think it's a can of worms and (to do it right) you'll probably want to buy a wideband O2 sensor (another $700).
Yes it's worth it in my opinion, but not too many others have put the time and effort that I have in to it. It's a learning process than can take weeks (at best) or months to make your car perfect.
No harness required, you can get it for $1250, but expect to buy a Wideband O2 sensor, which you can get from FJO for around $700, or from MOTEC with display for about $1200.

SpoonS, if you go this route, you really ought to hire CJB to do the tuning for you, as it's not a trivial undertaking. I agree that if done right, it's an improvement over VAFC's, but the learning curve is steep.




I will send you a PM.
