I think the point is being missed here somewhat.
This is aimed squarely at those folks who are handy with a spanner but want the benefit of having a complete kit, rather than sourcing the bits themselves, or those that have a good garage nearby they trust to do the install for them. I'm sure Abbey will still offer a drive-in/drive-out solution for those that require it, but for now this thread/kit isn't aimed at them.
From what I can see Mark this seems like a pretty well-priced kit, although may be better to offer it at the lower price for those that are too far away to make dyno time at your place a reality. That would give them a chance to go to their local place for a tune at least. For anyone considering going FI, this is a cracking way to do it.
