Unfortunately people want to know what the differences are between a universal program like the JWT vs. tuning a car and that means that it has to be shown. Undoubtedly it looks like were trying to 1-up the competition, which in all honesty we are, but the fact that there is much more potential in these cars from being able to tune them just goes to show why the Z has not been the performer that it has the potential to be. This is the year of the Z. =) Soopra what?
