    QTY

    Can the Holley HP control the OEM returnless style fuel system or will it have to be converted to a return style?

    Asked by: heytonyman
    You should be able to keep your current fuel system with this kit as long as it has enough pressure.

    so with the Holley Dominator being so close in price the difference is minuscule really, its huge Landry list of capabilities endless amounts of features it would seams to be the better option. Or is there any reason or benefit to this kits instead?

    Asked by: RogSRT8
    With this kit you will still need to provide the throttle body. EFI is superior in most applications. There are a number of complete kits like this option http://www.jegs.com/p/FITech-Fuel-Injection/FiTech-Easy-Street-EFI-600-HP-Throttle-Body-System/5109244/10002/-1

    Can you run e85 or alcohol?

    Asked by: CUNDN Racing
    The ECU can be used with E85, but your fuel delivery system will need to be selected to run E85.

    2003 Grand Marquis. 4.6L 2v, COP. I'm building a tube frame buggy with a T45 and I want a clean wire install. Any reason why this wouldn't work for my project? Would this be a push button start kit?

    Asked by: Hinz Fab Haus
    This would work for the EFI portion of your installation. Please review the installation instructions tab on the web page for more details.

    What about transmission management? We have a 4R75E behind the 4.6 and this kit appears to only take care of the engine. Is there a kit for both, or a separate controller?

    Asked by: Biggerman
    This kit will only control engine management. Transmission control would need purchased separate.
