Can't open the Facebook link without an account but thanks for the tip regardless.

I'm with @LeVeL on this. I don't have a Facebook account (nor am I ever likely to get one given the way they are) but I'd love to see more info about this, I've definitely seen the problem in a number of Ecoboost cars and I know they don't like topping off. It would be great to see how it's done!

There's gotta be something else going on. My car does not have a noticeable rough idle and I am at 46k miles and run Torrie's 93 and E30 tunes. I will say that when I watch the rpm on the SCT, it jumps around 25-50 rpm, but I don't notice it. I theorize that maybe those with a rough idle may have carbon deposits on their intake valves.

I see the same thing, maybe 25-50 RPM slight variation, more so when it's cold usually and it mostly goes away once warmed up (which doesn't take long). It's not enough to concern me at all, and it's really not even noticeable except I always watch for that sort of thing and usually have data logging happening. Someone just casually sitting in the car would probably never notice it in mine.

Nice - looks like a 1 beer job.
I know it's hard to quantify, but how much 'shake' does your car have with the solid mounts? Still family friendly?
I usually end up putting Poly motor/trans in my cars, and love how stiff they are for a few weeks. Then they start feeling 'soft', and I regret not doing solid...

Since my IPC upgrade and setting up Lincoln Drive Control, my wife absolutely hates Sport mode in my car to the point where I won't use it when she's in the car. I can't even imagine how she'd react if I threw an aftermarket motor mount in.

In fairness, she's probably a little spoiled by the smooth quietness of the car generally, though. I do agree with her that for general driving, if you're not getting into it, it's nice to just have a comfy, smooth ride.

Anyway I wouldn't even attempt a motor mount.
