Fuel mileage came way up, but when it's cold it still has issues......I'll get it right. Can't wait on VH to come around to an idea other than "Auto tune, Auto tune, Auto tune".
What truck did you visit? Who was the person you spoke with?
We design all of our maps for the use of a high flow air filter. When you initially install the map it assumes there is a high flow AC on there.This is not a problem having the stock. However, there is another feature. within the ECM called Adaptive Fuel Values. The ADV's will slowly trim out the fuel of the original map to suit to your current AC setup. When you install the new air cleaner, ADV's were set for that stock filter. This is obviously not the way you want the bike to run. So at that point of the new AC installation, we would have recommended flashing in the same map again. This would reset or zero the ADV's and allow the full potential of the map. This is all outside of the AutoTune. That is a whole other beast in itself.
