It doesn't surprise me one little bit. It's entirely typical of TMS, there are many, many similar stories around, on the VX and VXR sites.
Two respected European tuners (who don't like each other) are in agreement that he doesn't have a clue what he is talking about. Quoting 23bhp for a remap only on a NA 2.2 engine pretty much sums him up.
In terms of PR, spin, putting on a show, as a pure sales guy the bloke is fantastic, but there's nothing of substance behind it, no automotive or engineering background, just lots and lots of manure. I wouldn't trust the guy as far as I could throw him.
