Supercharger doesn't affect shift up RPM

I've been designing some superchargers for the Hopper, but I can't get it to shift up at 6700 RPM. It instead shifts at the original RPM of 5200. There must be a mistake in the code, but I can't find it. Here's the code:

Code:

 
"supercharger": {
        "gearRatio":1.35,
        "clutchEngageRPM":0,
        "clutchDisengageRPM":4950,
        "pressureRatePSI":500,
        "pressurePSIPer1kRPM":2.65,
        "crankLossPer1kRPM":0.04,
        "type":"roots",
        "boostController":[
            //throttle in %, factor
            [0,     0.2],
            [50,     0.71],
            [100,     1],
        ],
    },
    "mainEngine":{
        "maxRPM":7000,
        "burnEfficiency":0.31
        //supercharger name
        "supercharger":"supercharger",
    },
    "vehicleController": {
        "highShiftUpRPM":6700
        "revMatchThrottle":0.25
    },

Also, when I add the "lobes" function (copied from the Barstow SC), the Hopper gets a fatal vehicle error.
Thanks!
