I reckon there is some confusion here. I think some people are talking about having struts that open the boot fully when opened from the fob, and some are talking about the boot opening fully once lifted from the closed position.
I don't think having the boot open fully from the fob is possible (as much as I would also like this), regardless of what struts you put on. I'm pretty sure the boot catch is designed deliberately in a way so that the boot just 'pops' open and then you can lift it a little before the struts take it the rest of the way.
