3.5L EcoBoost - Ti-VCT?

For the SHO, do we have Ti-VCT or just VCT for the intake cam?
The reason I ask is my 2014 SHO stock calibration has it set for intake only, but the F-150's have Ti-VCT enabled. This seems odd because I thought all of the 3.5's were twin independent VCT?
 
That means Twin independent Variable Cam Timing. Some of the earlier Ford engines had variable valve timing on just the intake side.  F-150 Article.  Z  http://www.hendonpub.com/resources/article_archive/results/details?id=5791  The V6 EcoBoost engine uses two turbos, one per bank. These fixed vane turbos operate in parallel, that is, they operate independently of one another. This is unlike Ford’s diesel truck engines that use a turbo mounted in series, that is a smaller, variable-vane, high-pressure turbo to feed a larger, fixed-vane, low-pressure turbo.
 
I stand corrected.  The FSM refers to only VCT for the 3.5 GTDI engine for the transverse platform.  The F150 version (introduced in 2011) is Ti-VCT.  I don't know why the difference though.
 
Yea looking at Fords specs page looks like the eco probably vct otherwise they would be proud to put the ti-vct there also

What's confusing is that Ford compared the SHO to the Ford GT in a chart from 2015, and it listed the SHO as twin independent VCT. I think they did that also on some of the spec sheets. I looked at my engine and there's only 1 spool valve per cam cover, like the 4.6L/5.4L 3V V8 engines.

I'm not sure why they didn't make the SHO engine Ti-VCT.
 
To the OP,hope this helps any.  Z    https://drive.google.com/file/d/0B8JUL90DXgdiMTZ3a0wyU0JCYkZJN1ZTT3VEd3Fic09JNTlv/view

Probably a matter of timing, literally, and production commitments.  The F150 3.5 EB was introduced in 2011 MY, a year later than the 2010 MY for the SHO.  Also in production for the Edge, 2011 MY was when the 3.5L got the Ti-VCT setup for the NA engine.  But the Taurus 3.5 NA continued with the VCT system.
