In case anyone's interested, this seperator really works. Put mine on Saturday, took a 110 mile cruise on Sunday and just for the heck of it, checked the seperator. Had about a teaspoon's worth of oil in the bottom. My Mustang is a 2007 with just under 20,000 miles on it, change oil and filter every 3500-4000 miles, Mobil I synthetic and Ford filter. Always lost a bit of oil between changes, and now I know where it went-right to the combustion chamber where it could give the plugs and pistons a nice build-up of crud.

It ran 119.00 from JLT, with free shipping. They offer several options as far as finish and right or left side. While it may seem high, its a quality piece and looks like a factory installed piece, not something put together with hoses and clamps.
As far as the syn oil, I've noticed on various cars I've had in the past (always used syn oil) that some use a bit and some don't. My Taurus uses a bit but my wife's Subaru Outback stays full. Point is, the seperator really showed me what was going back into the intake, and now what isn't.

I empty mine about every tank of gas and collect about a half ounce of blow by liquids.
But after first drive on a clean bowl its catching some right away.
Keep in mind, my engine sees redline at least once per day (after its completely warmed up). My NA 4.6 3V is a carbon free zone!

Here is a thought for you. Wondering is this blowby oil in the intake could explain the startup blue smoke that we all have experienced sometimes with our S-197 V-8 engines? I like this unit!! CalStang

I picked up the JLT last month, I was getting tired of having to empty my little home depot joint every week. the JLT should last between oil changes and looks slick 
The black one looks nice and stealth

Some guys have gone open breather filters and put them on both left and right cam covers. Personally I don't want to be stuck in traffic in hot weather smelling those fumes thru the window or thru the AC, so I stick with a separator - on the PCV tube.

I just changed out my deletes today and with only 21K miles and oil changes every 3K miles the inside of the deletes tel the story about all that CRUD everybody is dumping back into their motors. This is the stuff that screws up the plugs on these cars.
Catch cans / separators eliminate 99% of this mess.

Whether a tune is to adjust A/F ratio or just tweak the ECM to counter the of loss of low end torque caused by removing the butterflies/air tumblers, I am not sure.
But I'd be finding out...I assume you're talking about the deletes - not a separator...
No a separator does not need a tune.

With the CMCV delete plates, yes, you need a tune. However, this thread (and I believe the question) was about the oil separators, and there is no tune needed with them.

Here's a couple of my install of the JLT unit, nice quality piece. I opted for just the can though as I needed to fab in the PVC valve due to my Centri unit.
Having ran the breathers I can tell you that you will get crappy residue under the hood and you will smell it. The seperator is the way to go IMO.
