454/502 MERCURY MAG MPI ECM UPGRADE
Description
Are you wanting more out of your 454 or 502 Mag MPI engine? Whipple engineers have developed a custom calibration for all 454/502 MPI's that maximizes the engines power capacity by increasing the RPM limit, increasing spark advance and modifying the fuel curve to give your boat a cleaner transom and a better performing engine. By optimizing the spark curve for 91 or better fuel, Whipple was able to extract 25HP more while not sacrificing stock reliability. The recalibration also features a 5400rpm limit over the stock 5100rpm which gives you plenty of prop choices. Whipple offers many custom calibrations for built and highly modified engines.
