Hello all,
I have a 2007 Grand Prix Supercharged that I am switching over to E85. I put in 60# Deka injectors and the high flow E85 pump. I have read a lot of posts and there really isn't a definitive way. I had good printouts from years ago but lost them. Here is what I did so far. I changed stoich to 9.67 which I read is the E85 reading. I changed the injector flow rate for the 60# in the tune. Is this correct and is there anything else I need to change. If so is there a write up on how to do it? attached is a copy of the tune.
