So i've been fighting this P0507 code. Its basically saying my idle is out of above the set point. This all began after i installed a hellcat TB 92mm.
When i first install the TB the car never threw this code but had the cruise control effect and surging at idle. I played with the airflow table, and also the small range table to get it idling fine and driving good. I still have a small amount of this cruise control/ throttle hang effect but its really not that bad. But now i keep getting this P0507 code, i changed some idle parameters to see if that help and also went back threw my airflow tables with no help and some start up/ cranking areas. only other thing i noticed is that the code only comes on when idling and never while driving, when the car is warm it idles in the area and rpm which it always has but.... when cold starting it does idle high for a few seconds and takes a while for it to come completely down to set point at 800 rpm. TIA
