Based on what others have gotten, I think I'd seriously question the 219 awhp with just a TBE (and no EM???). I've never heard of getting 50 awhp from a TBE. You'd have to be getting 85 or so crank hp from the TBE = not possible.
Did the same shop (and the same person) do both dyno runs? There was a great article on proper dyno setup. I'm not saying these guys did it on purpose, but some shops have been known to juice their numbers to make customers happy with their work. After reading the article, I was surprised at how easy it was to generate funny numbers.
