Yes all you need is the Cobb AP and a TBE, and yes you should install the exhaust first and then flash the ecu immediately afterwards. If you do drive the car without the Cobb stage 2 map installed make sure to take it easy until you can flash it. Without the Cobb stage 2 map installed, you risk hitting boost cut sooner and running into a lean condition.

^^^ i think its actually just the other way around. since the boost cut level is raised, you have more of a chance of running lean, then you do stock. thats my thinking.
