I have the same configuration and I was checking the possible causes. If you search the forum with keywords p0171, brz or frs, you will find the other possible causes. One P0171 CEL was fixed just by cleaning the MAF sensor. The other one was a vacuum leak under the intake manifold (a common problem with FI and there is a sticky in this forum). Search and go through the checks and clean ups, I am sure you will fix the problem. Good luck!
