I put the car in Sport + and tranny in sport auto. It was around 85 with high humidity. I'm the left side...that was my best time of the night.

Based on the stock times I've seen from magazines, the mods I put on my car pretty much did nothing. Stock this car runs 13.8-14.1 at 97.7-98.2!

Your trap speed is near stock for an 8spd Xdrive, 98mph or so, the ET would be about 14.0 stock. The magazine times you saw were for RWD cars, RWD will trap a bit better, Xdrive will ET a bit better.

The heat and humidity did you no favors.

But what about launching the car and shift points?

I am guessing you did not launch at a very aggressive RPM.

The intake, scoops, likely do nothing. The catback is worth maybe a few hp, you are relying all on the BMS basically which should net a 3-5 tenth improvement.

You had less than an ideal environment. I would say your car driven to its potential in better weather should net a 13.4-13.6 at 102-104.
