I like AMD but I have a feeling their rollers can be a bit optimistic - although not sure that massively out, so it may be you've got lucky with your car, and maybe others would see less on the same map etc.
I had a Mk4 Ibiza Cupra make 215bhp after a remap on AMD's rollers, they are 180bhp stock admitedly, but even so, it was more the 200-205bhp that would have been expected...
That said, im not saying its right or wrong, must be a good map... Might get myself down there!
