I am considering purchasing a 2015 Audi A3 2.0 TFSI. Does anyone own a 2015 Audi A3 2.0 TFSI and have the APR Stage 1 ECU Upgrade installed? If so, how has the car handled the extreme increases in HP and TQ? APR claims the Stage 1 ECU upgrade with 91 octane takes stock 220 HP / 258 TQ all the way to 305 HP / 371 TQ. I am a little concerned that the factory dual clutch can handle such increases. I mean that's greater than 40% increase in HP and TQ and stock 0 to 60 from 5.8 seconds to under 4.5 seconds. I'm also concerned about the stock brakes that come on the A3. Thoughts?
