^^^ I would offer that there is a pretty good reason for not constantly switching to the latest and greatest stuff on the market. I imagine they have several parts in inventory and need to sell them before they change their technology. Not that your idea isn't great, but just switching technology before the sales take off, is a recipe for paralysis as a company.
If they changed parts, they would be much farther away from full production and competitors would likely beat them to market.
What is interesting to me in all of this, is what the various players (those we know and those we don't) have in the works.
I remember in 2005 when I was a mere lurker on the board, that the general consensus was the Lotus ECU was too smart for tuners. Changing the car meant less power and the only way forward was less mass.
Now we have cars on the road that are knocking on 400hp. Not to mention some streetable/trackable/reliable options for us mere mortals that are knocking on the 300hp door.
I'm still a wimp though and haven't pushed the button on a kit yet. Given the current situation (VF - BOE - others?) I am glad that I haven't. One of these days though. One of these days.
