Hi just looking for some info on these obd2 aps and how accurate they are. I am using the obdlink MX Wi-Fi in my obd port and Dashcomand and Obdlink aps. These aps seem very responsive and work well but are they accurate. According to them I am hitting 310 hp now if they are accurate would that be to the wheel. Any opinions are welcome and no I have never dynoed my car yet but it is sothing i want to do
