It has to have the highest quality oil, no errors registered on tech2, and brakes and suspension have to be 100% in shape. Most people don't take good care of their cars, so if the car is somewhat worn, wear will increase even faster with the higher power output. If the car is in perfect condition, it will cope just fine. I'd also check with the seller, and double check with the manufacturer, that this fits your gearbox. Autos are weak, and if you increase power too much, they will break. Stage 1 is usually maximum for the 2,0 liter autos, with the higher potential for power in the 2,3, you have to be very careful not to add too much torque when tuning. Kristian
