^It's about more power on lower boost, and therefore efficiency per unit of added air and fuel, not the absolute figure. 9psi on two disco potatoes is 9psi on two disco potatoes, whether that's from a GTM kit or an F.I. kit. Difference is in the what makes up the rest of the setup and the quality of the tune.

And the stage 1 FI kit still uses 2860; GTX turbos are an extra-cost upgrade.
