You should recalibrate your TPS, its stuck at 44% when your car is 'idling', its not actually idling due to the TPS Value being above whatever you have it set as.

Your MAP is stuck at 85 as well, and does not move. It should be idling around 30 kPA ish, you may have a massive vacuum leak, or the MAP sensor may need to be recalibrated. You should probably go back through the startup process and recalibrate your sensors.

Also, what injectors do you have? Are those used/eBay RX8 injectors? Those can be fake/messed up and provide inadequate fueling sometimes, also could cause issues.
