I am looking for a tuner for 2015 Fatboy lo mechanic friend recommended TTS I have used pc5 with Autotune on my old bike never had it put on a dyno bike ran great. Is their a need to use wideband sensors on the TTS tuner or will it work well with factory O2 sensors?

 

It will tune well with just the factory sensors, The Wide bands can do more in some cases less in others, but must be used by someone who knows what to do with that information. Understand that tuning a WOT AFR is the easiest part of tuning and the thing that you the rider uses the least.

 

2015? You already have all the hardware you need to make a great running bike.
Now purchase a TTS Mastertune and do a couple v-tunes and you are done, with a smooth running, responsive engine, and a mileage miser to boot.
Add on a do-dad that needs a bunch of extra hardware in order to tune the bike and you end up with a decent running bike that gets lousy mileage that may run better than before but no guarantee.

thanks for the info TTS mastertune looks like the way to go already have high flow air cleaner sitting in the box. Bike has V&H slip ons so tuner has to go on at the same time. My real concern was what size bungs to have put in a D&D Fatcat I will put on the bike soon!!!!
