So ever since I started tuning my car with GC lites and BQ, I have had an issue where either bank #1, #2 or both goes rich post shift. So instead of having an afr of 11.x, it goes to 10.x. Whichever bank is doing it sees a flat lining STFT. It never happens if I just do a 3rd gear WOT pull. It only happens post shift. Sometimes the rail pressure even drops to around 1500psi as seen here:

Here's a continuous log with some examples of the riching out post shift.
