Well it turns out that they do not remove or up the rev limiter, so that is a fallacy. Also they do alter the fuel curves to utilize premium gas and change timing curves as well, at 400 rpm increments. They do the changes so that there is a difference at part throttle, which is where most of the driving is done, and full throttle. They claim up a 10% increase in hp for the NA. Now i do not know what they do to the TT ecu but for the NA they seem to do it right and at almost half price of JWT. Again, they DO alter fuel and timing curves.
