I had the AMD Stage 1 remap on my 03 S3 225 to take the bhp up to 260 in May this year. When I had the work done AMD replaced one of my boost hoses, but it only outputted 230bhp on the rolling road. I was told this was because the engine was now hot and it was not possible to get a genuine reading. I brought the car back 5 weeks later to have the 50k service carried out and specifically asked for a rolling road read out to show I was achieving 260bhp. I left the car with AMD on Saturday and picked it up on Tuesday evening. When i arrived to collect the vehicle I was told that it was only outputting 234bhp (test 1 226bhp test 2 234bhp) and that there must be another boost hose leak but AMD had not had time to change this. I can't help feeling that I have paid the best part of£500 for a 9bhp upgrade and did not detect any sense of responsibility from AMD to ensure the car outputted the promised 260bhp.
