Looking at the speed listed in KPH on the dyno sheets, you were going roughly 164-168 kph before the dyno ended. That is roughly 102-104 mph and seems to be around the top of 3rd gear. Maybe the print out is wrong. Do you have any print outs in RPM instead of KPH?

The only thing I can find on the 2FCA/2FDA codes are someone posted they might be HPFP related. Possibly a precursor to it failing, but I counldn't find much info regarding them.

Once you get some logs, we will be able to hopefully give you some better advice. Merry Christmas!
