I am very sorry to hear of this. Please shoot us an email or give us a call so we can look into this further for you and anyone else that is having trouble with their tunes as well for that matter. If the LOR has dropped noticeably and the kr has increased, I would definitely try getting fuel from another station and possibly try throwing in a few gallons of higher octane fuel as another member on here mentioned if available, to see if the issues have been alleviated. I also wanted to mention that it's worth trying a different fuel station for guys that have suddenly developed an issue that was not there when the initially loaded their tune. We've had experiences with sub par fuel even from the top tier or best stations in town, this time of year especially. I can honestly tell you that the no name station on the busiest corner of town always has the best gas in our area. They have lower prices than most and are in a great location, so it's that station that always has a line to get to the pumps during rush hour everyday. We have been using this station to get 93 pump gas for cars on the dyno here and have never had issues with a single fill.
What some people don't take into account is that those top tier / big name stations typically cost more and therefore do not have as many people filling up with premium there. So their gas may be sitting in the ground longer than the brand X station down the street that has fresh fuel coming in twice as often due to volume. So if you have always been using the same station and notice your vehicle's performance suddenly taking a change for the worse, by process of elimination that would be the 1st thing to try if you haven't already.
Don't get me wrong, I"m not blaming the fuel or the station for the issues that the vehicle has started experiencing , just wanted to share the experience that I have seen over the years with different fuel stations and winter weather as well. Also keep in mind that in years passed we had released cold weather specific tunes when needed, but the version 10 tunes did not have cold weather issues reported last winter after it's release in the fall of 2015. We can however make adjustments to the tuning if needed to offset what ever issues the cold weather has brought to the table. We just need to know about the issues or we cannot do anything to help.
