I have included a cut/paste. This sums up my thoughts before I even went to the site.
Anyways, I like my Carb'd bikes because no one has offered a tuning device that works for the REAL rider. I want drivability, not JUST high horsepower numbers.
The fact that this is dial tuned is a plus for anyone that wants to have impressive throttle response. And in all reality, it's the crisp throttle and increase in mid-range that you think is "horsepower", generally speaking, jet kits and programmers aren't designed for horsepower but rather to increase the throttle response, mid-range and drivability characteristics, and allow for intake and exhaust changes.
So, YES, the Powercommander is a superior tuning product, but how many of you are really gonna use it to it's FULL, let me say that again, FULL potential? If you are ALWAYS gonna ride above 12k RPM then cool, but if you ride stop and go traffic and cruise the streets, then the TFI "may" be a great new option to the tuning world.
"The TFI box (that stands for Techlusion Fuel Injection) is made by the guy that founded DYNOJET. Besides the obvious, the price, the TFI works really well on your real world road bikes, whereas Power Commanders were designed for race bikes which could be used on road bikes, this TFI box is designed for road bikes. This means that you are going to get a much more defined and accurate set up for real world riding. And with a working accelerator pump circuit, reacts like a finely tuned carburetor."
