    L99 throttle running away

    So the car is a Procharged L99 with pretty aggressive cam. The car cam in without any issue and we did a flex fuel kit on it. I adjusted some basic things for the new injectors and turned on the fuel sensor. Everything else in the tune remained the same.

    The car takes off without giving it any throttle. It'll start to pull and swing through gears. When we turn the car off and do a koeo scan the tps sits at 30%. Is there anything I can do to reset that? It seems super high and I'm guessing that's why the idle runs away. Sometimes in park it'll idle up to 3500rpm and won't come down.

    If you can look at the tunes we changed the injector size and turned on the flex fuel sensor. Is there anything we can do to stop the throttle from running? We swapped throttle bodies and it still happened. Could it be a bad pedal?
