I’ve got a 2019 GT and the car runs great. My only issue is whenever I take it out for a drive, whenever I go to back in to my garage in reverse, the idle fluctuates up and down by about 400 to 500 RPM. It doesn’t try to stall out, but it is going into higher RPMs to make the car surge backwards. I can be in park, neutral, or even stopped in drive without any fluctuations though. Maybe just something with the E85 tune or something else I should check…?
