Thanks for the info but I actually know how a turbo works and a "blower" and a centrifugal supercharger etc and have built several centrifugal supercharger engines . I just don't know anything about computer operated vehicles as I previously mentioned.

I didn't notice but I will check it tomorrow and let you know but I'm sure it has sufficient boost at high rpm . As I mentioned in my first post, it hauls a_s above around 3000 rpm just like a production turbo car engine should.

Well, you don't know how a turbo works if you're saying it makes a little boots around 1800 rpm. You can have a turbo at max boost under 1800rpm. You also don't understand turbos, especially these turbos if you think boost is dependant on RPM.
Don't worry, I still believe in you.

Also, I am not aware of a production turbo vehicle made that has the turbos max out at under 1800 rpm but I suppose that is possible.

What kind of "engineer" are you again?

This is exactly why you don't understand this turbo and why you have smoke blowing. There are plenty of reasons why you could be blowing smoke, and the turbo is one of them. Again this turbo is not like standard turbo and is nothing like a blower of any kind. If the turbo is messin up you can actually overboost at very low rpm.

I also obviously know that there are plenty of reasons why it could be blowing smoke so this is not a revelation to me.

It depends, this is not a standard turbo nor a blower. Boost is not dependant on RPM and if the VGT is 'confused' it can be anywhere in a wide range. 5-10 under light throttle and up to 28psi at full throttle
Do yourself a favor and youtube a VGT or VGT turbo, VGT stands for Variable geometry turbo, use whatever kind of engineering background you have and let that acronym sink in and maybe you'll understand what RPM and boot aren't fully dependant, espically when not functioning properly.
Could be the turbo trying to cycle. if it's coming from where I'm thinking. could also be a blown bellow on the up pipe.

Ok, I found several vids on this type of turbo . It is a very simple but ingenious concept.
I guess that if my boost is determined to be extremely low at low rpm and there are no leaks in any of the hoses, the variable portion of the turbo is not working for some reason and the ticking sound is related as you think it might be which I'm guessing is a very loud relay.
I also just read that it could be the "EBV" sensor instead, do you know if this is possible?
Just out of curiosity, have you heard of this portion of these turbos going bad, especially at 100,000 miles or less?
If this is what the problem ends up being, do you know approximately what the worst cost scenario would be?
What could cause the turbo to "cycle"?
Thanks again

You can try cleaning it....
It would be best if you can get an elm device so you can look at the live data. That way you can see what the computer is requesting and what it is detecting.

EDT: also, to answer your question, one of the updates that Ford did adds a procedure on startup that cycles the vanes. This is to help address the sticking issues.
