hi, your car must be 150 hp ,you can make it 180-190 hp with remap ,no parts the change ,it is just a software ,it increases the turbo pressure so both the torque and hp increases ,i think it is around 600 euros , but be carefull with the gasoline you use , after the remap ,also becarefullwith the sercvice times ,the engine will be sensitive after the remap both for the service and with the gasoline ,but if you will be carefull about them there is no problem ,i think it is great 180-190 hp ,but you should find a profecional remapper ,most of them does not know too much thing ,the put the same chip too every car and then change teh soft ware so ,if possible make the remap with someone whosswe experienced in remaping audi and refrences
