Just got my first Harley recently that came with a SE Pro Tuner is there any advantage of upgrading to a TTS Mastertune - My Harley only at stage 1, Stage 2 not for couple of years - Still a beginner with the SE Pro Tuner

Swap to TTS and you will be even more of a beginner.

TTS is good but steep learning curve.

If you can get to a dyno guy who is any good , find out what he uses before you think about changing then you have backup .

If you are going to have it tuned by a professional tuner, then find one that knows the SE Tuner. If you want to tune the bike yourself, then learn how to use the turner you already have.

Customer support is an area the the various HD tuner systems over the years has fall short, which is the reason I went with TTS about 5 years ago. - Rob

Ok Thanks
