    Just wondering how accurate these aps are? I am using the obdlink MX Wi-Fi in my obd2 port. The aps I am using are Dashcomand and Obdlink and they seem to be very responsive. According to them I am getting 310 hp and 315 ft-lb of torque. Now if this is accurate would that be to the wheel? All options are welcome I have never had my car dynoed so I am not sure what the real numbers are.

    Polling speed the adapter matters more than the app. Wired had the fastest PIDs.

    I have no idea about the numbers, but those seem synthetic. My guess would be like %18, +/-%2 drivetrain loss on a FWD.

    you still dont have those numbers. cammed with intercoolers or e85 and heads fight to hit 325.

    thats the only true way to know what hp you got. and even then brand to brand, dyno's vary.

    pretty sure you need to lean out the fueling when spraying or you end up to rich.
