So on the performance front my next goal is further increasing my efficiency. my next project is a diy 100% water or 50/50 water/alcohol injection setup. I weighed e-85 and water air intercooling and several other options and this is the route I'm going to do. free power/knock reduction/steam cleaned engine? yeah I'm down. I probably wont even need to touch my tune and and still gain power. its going to cost a fraction of what the name brand kits cost and have the same reliability.
