There are few universal truths, here's one of them. Those who buy other FI units quicklywish they had bought PC3. Those who buy PC3 never look back. You're like us. You're gonna need the PC3 because your inner speed-freak will freak-out if you can't maximize your go-fast parts. Plus you're gonna need to maximize your fuel mileage too. The PC3 gives you both capabilities, plus it is set-up to let youadjust the air:fuel ratioacross the entire rpm range from above-idle to wide-open-throttle. Save a couple extra bucks then buy it.
