IUm struggling to see why you would choose this over a K04 £/bhp wise.
I see what you're saying and I'm not saying it's wrong, but there's definitely an argument for "Why not? Let's have a go and see what happens, it might just be good" after all, if we all did the same thing and never investigated anything new, the world would be a boring place and we'd never make any progress. Niki has already hinted on his Facebook page that if this is a success (and don't forget this is at R and D stage according to the header on the dyno chart) and performs well, this will be the best, easiest and cheapest upgrade for the TFSI, possibly suggesting that it will come in cheaper than a K04 conversion.
