Not sure what you are asking. Harley has pre programmed maps for certain SE upgrades that they can reflash your ecm with to save you from having to retune your bike using some other method. If you have a TC 110, usually a cvo bike, you shouldnt need a reflash. What changes have you made to your bike?

 

you get the same benefits on the 110 that you get on the other bikes. better throttle response, more power, more torque, cooler running, etc. and yes, you would rather have a reflash, either by tts, screamin eagle, power vision, etc. than an add on box like a pc3.

 

 

I understand, your question was about an aftermarket tuner.

 

I've got a 110, as do many of the folks on this board. I would imagine that the majority of us have done a stage 1 (at least). I can't give you specific numbers as I did not have a dyno tune done, but I have flashed my bike with the power vision with a map supplied by Jamie at fuelmoto. the tangible results were as I described, and also included running cooler (forgot to add that one), and gas mileage had no appreciable effect.
