Not that it's a big deal, I'm just very curious why my car ran like absolute steaming caca on 93 instead of E85 last night.
Was headed out to the track (about 70 miles away) and had a little less than 1/2 tank of E85. Shoulda known better than to not fill up before leaving. Could not find e85 anywhere around the track and the track doesn't sell it. So, I went in search of e85, but was running dangerously low on fuel, so I stopped and put a gallon of 93 in. Still couldn't find any, so I ended up stopping again an putting in 4 gal of 93, disconnecting ECM, changing chips to my TT 93 chip, and turning boost down all the way. Don't know what boost ended up at with the gas because I didn't go there. Anyway my BLMs went through the roof (142), and the car idled like absolute crap...almost to the point of dying at a light. Got close to home and filled up with E85, disconnected ECM, changed BACK to the E85 chip, and started. The difference was night and day. Car ran like brand new on E85. Any ideas as to why it would run so shitty on 93? I know fueling is different in the chips, but this was absolutely terrible.
