I don't think I'd take a swing at that wasp's nest. There are so many long winded debates. In my opinion the answer is always the ECU that you can get the best local support with.I always watch these on youtube when they come out. Good info. A video suggestion is AEM vs. ProEFI.
Jay, Let's say you are comparing a perfect 3 port that does not allow any oil through with a 2 port can vented to atmosphere.The sealed can would be great if you could ensure that no oil was being pulled into the inlet track. The vented cans are "easy" because you can't screw it up. The other issue with a sealed can is IF it works for one guy at his power level there's no guarantee it will work for the next as both engines could have a different level of sealing producing a different level of blow by. To me it's not worth the risk of pulling oil into the inlet track as it hurts octane too much.
