I am, but I don't think it has anything to do with it. I have been running an ESS tune now for many months with no problems at all. The only mods I have are the tune and an AFE filter...well wheels but those don't count. I have just been driving my car like a daily driver recently, nothing crazy. I do drive 40 miles each way to work, and it happened after I drove out there, of course. It could not happen in town!
