I've done some lurking and haven't really found an answer to my question, figure it's worth asking to save myself from doing something stupid. I've been looking for a tune for my Speedmaster as I have recently deleted the airbox, thrown on some K&N pod filters, and British Customs British Bomber exhaust. SAI is removed, and I am blanking off the O2 sensors, so pretty standard stuff. Problem is, I haven't been able to find a good tune for it. TuneECU pretty much offers tunes for aftermarket pipes, TORS, or productions silencers only for this bike now, and doesn't go into much detail about the tune itself. TTP has a much better offering, specifically tune 13, but I contacted one of the guys that works there and he said that the tune will run too rich unless I have DNA podfilters. I'm not too keen on spending over $100 on another set of pod filters and $150 on a tune that may or may not work, does anyone either have experience with this tune and can give some advice? I was also thinking tuneECU has one for a bonny, same engine, that lists everything that I have. Can I use a bonneville tune for a speedmaster? Or are the cylinders laid out differently? Any advice is greatly appreciated!
