Looking for suggestions on a tune (map) for my 2011 Speedmaster EFI with slash cut long pipes. Rather than replace a bad O2 sensor, they are are being removed. Bike still has secondary air injection, and that removal is planned for later. (Need to ride now!) From what I have seen on the internet it may already have been mapped because of the slash cut pipes?? I assume that O2 removal requires a new map. Any sources or suggestions are greatly appreciated.
