I had my A3 quattro AMD Chipped a while back, very pleased with the result. Since having the car in for a variable service(Audi garage), plugs, filters, brake fluid change, MOT etc, the car feels sluggish when reaching the end of the rev range whereas before it would power all the way.
Is it possible that they have reset the ECU when resetting the service alarm, is there a 'default' type reset ?
It's still quick just not to the extent of before.
Any suggestions appreciated, i'll be giving AMD a call later to see what they think.
