I believe that most guys know about the added performance with the injection, although I will try to find some comparisons. I am not naive to the fact that without installing the TWM yourself that the cost approaches 10k. This was a big consideration when I purchased mine.
On another thought entirely, until Congress allows us to develop the offshore (off Florida where the Chinese are drilling) and in country
oil reserves, we are going to get into further trouble with our economy. I really don't understand the thinking (or lack of) behind this. It's not ecology, it's big money!
