Ya, that tuner is more of a cool gadget for me. I currently dont' have plans for engine mods or A/C, exhaust mods. Access to the ECU is what I would really be after here. The TTS allowed you to calibrate your speedo (like if you changed wheels) and turn the engine heat management system on or off along with adjusting many other tables that control the rpm, AFR ect... Data logging was also pretty cool, but from what I understand the 911 tool has some of that data logging capability. Learned a lot of real cool stuff about my bike that way.
