    Nice pictures of a great engine especially EFI.

    One way to trick the fuel computer some is more fuel pressure.

    When any modifications are made to an early EFI motor such as your comp cam the original fuel mapping may not be adequate.

    More pressure delivers more fuel flow during each injector pulse.

    There are a few other ways to fool the computer but they are limited. They work great for factory applications.

    You can change one resistor in the ECU and set the fuel where you want. Change it as you drive even. Info
