I have found promised bhp increases are rarely exclusive to one item. They are normally achieved interdependently through a package of tweaks rather than separately.
That lessens the individual tweaks effect and makes dynos the ultimate humblers, though still the very best tuning devices and LOTS of fun, which you are certainly having.
Do you intend to try each one by one? I look forward to the tale of your adventure.

Have a re-read of my post Lorn, what I've already installed is very much a carefully curated and extremely well proven package of components designed to deliver 200hp+ on the 2.0 Duratec. The same approach has been used by a multitude of trusted tuning companies going back almost 20 years in the case of Mountune, all are highly experienced with this engine and all make 200hp + using the same package of components I've deployed on Monty.!
Thank you for your reply Monteque. With respect, the point I was trying to make was that promised bhp gains often depend on other things being done AND that
it would be marvelous for this community and others to know the effect of these changes individually. Decades ago, Luddite drilled into my head that
one should never make more than one change at a time away from a working datum. I am infinitely lucky he did so. Methodology is more important than results.
It is sad, simple logic.
The one does simultaneous changes, the less knowledge is gleaned from each one and the frustrarion risks increase factorially. For example, one change that goes awry means a quick return to the working model.Two change is a bit harder to return. Four changes means 1x2x3x4 or 24 different possible results. I realize that dyno time is costly, but a one-by-one approach is ultimately more instructive, worth the extra money, if only for posterity. Doing all at once does not underline the efficacy of any separately.
Think of it this way. The first time I tell someone that they must buy/install many things, they ALL ask me WHY for each and that is not unwise of them. You have an opportunity here to lead MANY car owners.

P.S. GoMoG LAW of TRUST Trust no one but the relative differences on a rolling road dyno.
