Has anyone else used TTS master tune?
I have a 2011 XR1200X with V&H "Widow" pipes & K&N AF element. Like many here I tried the V&H FP3, it had one map for the pipes.
It ran a bit better at high RPMs (5K+), but it didn't help the annoying sputter at low speeds (30MPH second gear). I tried auto-tune, didn't help (some V&H reps said "the 02 sensors are in the wrong place") WTF? I tried two "custom" maps made by the V&H technicians, but not much help either.
After finding a local dyno tuner (Hayward CA), they said the V&H doesn't allow for enough adjustment for a proper dyno tune. They said to buy the TTS Mastertune for the XR. It was another $300, but long story (somewhat) short, Jim at Metal Dragon tuned my XR and got rid of most of the annoying sputter.
And, like many here, my XR was running very lean in the 2.5k to 4.5k RPM range, that got fixed too. And I got a few more ponies and ft. pounds! The TTS is not simple to use, so it's better to have a pro do it, but if you have the skills you can try it yourself.
I'm curious to see if anyone else has used TTS.
