After installing the Two Brothers Racing pipe with no Cat and putting in the Power Commander PC3 usb with custom map, my engine now surges when idle. When I monitor the rpms at idle, they will bounce from 1000-1500 rpms. Using the PC3 software, how can I adjust the map to give me a more consistant rpm idle speed? I want to stay around 1400 - 1500 rpm's unless that is not a good idea. Thanks.
