drove the car around for couple of days since getting it back. No issues so far.

I did notice the LT fuel trim is higher than before the recall. Before it would range from +1% - +6% at idle/no throttle. now its at +11% - +12.5% at idle. Does anyone know know what is the ideal LTFT range for the car running on e85? I'm still a noob when it comes to tuning. I tried to find answer in posts but nothing concrete. Also the LTFT changes(drops) when applying throttle vs idle. So when I monitor the LTFT should I monitor the idle LTFT or LTFT under throttle?
