heres what i did bought brand new v&h pro pipe bp se heavy breather and a USED pc5 on here put all on and bike idles like **** skips and farts and only runs deccent above 2000 rpms i took off the pcv and put the 02 sensors back and it runs fine i downloaded the map powwercommander said to maybe the pc is junk?the dealer said dont worry about the warrenty on the bike without the pc but wouldnt it run even better with it?i dont want to spend money for dyno run cause i plan on going to 103 ond cams next winter any suggestions

 

Get rid of the power commander 5 with the auto-tune, & get yourself a TTS Mastertune & have the bike dyno tuned.It will run top notch!!!You will have to find a tuner that's fluent with the TTS though!!!
