    John,

    I checked a few things tonight.
    TPS: I'd been calibrating it using the cam lever on the linkage. However when I tested it, it was only to 85%. I recalibrated to get a full 0-100% movement.
    Injector scaling. My initial setting was 200cc/min which equates to 169bhp (per Emerald). However, I'm running 320cc min injectors provided with the kit. So, should I tweak the injector scaling to reflect the 320cc capacity? Also, should I change it to 2.75 bar fuel pressure (40 lbs) which is what I'm actually running or is the 3.0 bar default sufficient?

    Thanks again

    Jason
