Hey what's up Burnie. Im now running stg1 aggressive map also but I am using the linear throttle map. The stock throttle map lets you push the pedal down less to get more power. I like the linear better since it feels smoother when I press down the pedal and when I really press down the car goes into take off mode. The sport mode was fun but I'm going to keep mine in aggressive mode. If you are worried about the boost, which ive see other cars running 16-17 psi max, you can datalog a couple of runs and send them to Cobb or post them on their forums for examination.
