I recently got a lethal o/r x and an sct xcal. I contacted Shaun at AED and he had me data log the car and send him the files. After reviewing the files, he said they look like I was using bad fuel. Before the first log, I had bought 93 octane from a convenience store selling Shell gas. I then went to a Chevron station and filled the tank with 93 octane. I data logged it again and this time he said that this was just as bad or worse. I am thankful I went with AED instead of someone else who would just sell me a tune without looking at my data logs first. Had I done that, I may well have been the next #8 failure. I'd like to know if anyone else has had this trouble. I'm gonna be pissed if I can't get a tune because I can't find anything but shitty fuel. Any input will be appreciated.
Thanks
