Sorry for the double post didn't know it went through the first time. I seen about 165-175 on e85. I'm currently running 93 and first time I switched maps to 93 my MPG seemed normal, it's only here in the last month or so iv noticed it drop hugely! I just filled up, and I'm on 3/4 tank and only went 24 miles, yes I let my car warm up a bit since its cold but no more then prolly 15 mins total a day. I have all the mods required to run e85 not just a tune.
