    Default New Guy - Michigan - Holley HP EFI

    I'm a new forum member from Farmington Hills, Michigan. I go by RacerMark
    I have had the Holley HP ECU fuel injection system for about 2 years.

    This is my car info:
    69 Camaro SS (Street/Strip Car – Runs 9.43 @ 148 MPH)
    BBC 522CI with 8-71 Blower & Bugcatcher (No IAC Valve)
    MSD Distributor with Magnetic Pickup
    MSD 6AL Digital Box
    Holley HP ECU Controls Ignition (Idle Spark Enabled)
    160 lb/hr Injectors
    I'm very happy with the Holley HP EFI fuel injection.

    I just bought the Holley HP system and have a similar setup, It's a 505 Pontiac with a BDS 871. Did you use a lot of AE vs MAP Enrichment or did you use AE vs TPS mainly? Just curious how people are dealing with the large butterfly openings? Thanks.
