I believe the Cobb AP has the VF34 map, so just flash that in to your computer and see how she runs.

My advise is to get a protune with your setup. You cant adjust the boost with the AP unless you have the street tuner software. A protune will net you the best hp and torque gains.

Over all the Cobb OTS maps for turbo upgrades leaves alot to be desired, after you get everything loaded into the car go get a protune and you would be looking at alot more enjoyment than if you just load in the OTS map. 20-30whp gains can be had just from a good protune on the VF34 maps, from what I have seen.

Flash in the vf34 ots map for now. Buy an intercooler (ssautochrome tmic) and then go get protuned. I would also suggest you look into a catback exhaust to go with your downpipe.
