I have a 2001 AMK 210hp s3, the performance is reasonably good. But the car seems to rely on revs rather than shove, I am reasonably sure it is giving the correct performance. I did time to 80mph and the performance/power output was about right. I just have this overriding doubt that chipping it for 260hp from the likes of AMD is going to be a waste of £400, I will spend the cash and the difference will disappoint. I appreciate that it is difficult to give a true descriptive value on the difference between a stage 1 modified car and a standard one. If you keep on adding hp and torque it is then becomes easier to imagine the increased performance, but what will 60 odd horse power and torque give. Can anyone convince me to part with my £400 ????
