ok guys I know stoich for gas is 14.76 and for e85 is 9.76 so why would my tuner put 10.50 for e85? I am new to tuning but I also took the tuning school course and now that I look at this tune I'm don't understand some of the things. like I said I'm new to this but took the course to be able to tune the car myself. ive paid over 2k in retunes and its been the same thing everytime. car is a 06 gto ls2 with ls3 top end. heads milled to 63 ccs and fully cnc ported and gpi intake ported and rod mod. tb is also ported. full bolt ons. 4000 stall. 3.90 gears. now this tune that I'm gonna attached is before heads were milled to 63ccs and head gasket from .54 to .40 thick. to bump up my compression to 11.5. cam is custom grind 239 254 so its big. I did a lil log just drove it around for first time just to get a feeling for it and it sure feels different. I'm gonna attached the files and see what you guys think and what you would do different. I want to try do it myself with your help before taking to another tuner. like I said its on e85. thanks in advance
