Now have 14K on the bike.
Non Ethanol 93 Octane Local Mom and Pop Grocery Store (Sparkle Mart): 47-51 MPG (Highway) 42-45 (City)
Fullsac 2.0 Baffles with Stock mufflers, Decatted Stock Head pipe, TTS map from Steve.
10% Ethanol 93 Octane (Usually Chevron):
37-39 MPG (Highway) 31-34 (City)
I am really fortunate to still have real Gas avalible locally and using Pure-gas.org I dial up locations wherever I am to find the pot of gold. Sometimes a wild goose chase but sometimes the hunt is better than the kill and rolloing down the road the engine noticably smoother and will tolerate lower rpms where on ethanol blend runs noticable harder. This may be a by product of Steve's map for the mods I have done but more info would be needed to determine how close this map is with fuel type, octane rating, temp, altitude, etc. from the dyno run. I know with the system it is able to fine tune adjust on the fly but that map is pretty damn close to what I want out of and expect fuel mileage wise.
The only observation here is that I get a little rumble and a pop coing down through 2K on the decel and I can live with that with the mileage i get overall.
Just a few thoughts....
