What Tuning Mods Needed with 15% Ethanol?
Well I have been happy for years. Now I hear 15% Ethanol is coming. What am I going to need to check in my tune.

GM never made any calibration changes for E10, so I doubt E15 is going to change much.
Every GM vehicle since MY1992 has the parts to not be physically degraded by ethanol.
E0(100% gas) has a stoich of 14.6. E10 is 14.2, E15 will be slightly richer.
