i voted "ECU", b/c... 1. i'm planning on buying one next year (thinking of speed tuning, but haven't really done my research) 2. i want to know exactly WHAT i'm buying. i.e. i wanna know what the chip does, and how it does it. Blind (promise of) horse power numbers don't mean much. In depth review of chips would be nice. And overall, i think it would be awesome if we have an in depth review (pinned) for all of the above. Since these are the most popular upgrades and most asked q's... it only makes sense.
