Its a simple fact that typically factory FI with small displacement will not compete with aftermarket FI and large displacement.

Factory FI is not typically meant as a straight performance modification, it is for the aid of gas economy and performance whereas all aftermarket FI kits are developed for straight performance.

Our cars with mods can handle the 5.0 in decent trim but once you strap on FI onto the motor it's goodbye 335.
