if you have had idle AFR of 14.0 ish for the last few months than that is about right... what is happening if i were to guess is that thhe changing weather is causing your car to lean out at the top end... if i were to guess i'd be it is at the top of third gear...

your custome tune on 12/12 will be good for it. tony at eurocharged, myself and distantpulse will be working this week to take care of distantpulse's bit of a leaninig problem. it should give tony a good starting point for your tune once we get his dialed in this week...
