Ok, great info. Might switch to the TTS. Now I would like to know what the difference is between the TTS and the DYNOJET POWER VISION? The Vision has that nice info display and can switch between maps on the fly. Like a performance map and a fuel saving map. Which one is a better unit?
Coke or Pepsi?
I have both the old-style TTS and a PV. My FXSTB was tuned using the TTS. I self-tuned my FLHTK with a TTS. I'm tuning with a PV on my FLHTCUSE7. They're both very good, very powerful tuners. For self-tuning, I think you're better off with the PV. The display makes it so much easier to quickly fill in all your cells when you're doing a tuning run. The interface is ridiculously simple, and you don't have to get off and on the bike every time you do a run.
While I like the MasterTune software a bit more than WinPV, it's nice to only have one program you need to use (rather than MasterTune, DataMaster, and V-Tune).
And then you've got the additional benefit of the gauge display on the PV if you're so inclined.
They're priced within a few dollars of one another, but the PV comes with cables, bar mount, and the display.
You won't go wrong with either one, it just comes down to what you're more comfortable with.
