remap, maf sensor advice

[accy]

When i had my audi A4 (130 bhp) remapped, the guy said the maf was out of speck and change it when i get the chance. He still went ahead with the remap and said it should not make a diffrence when i put the new maf sensor in.
Now it feels like i don't seem to be getting the same torque as before.

If you know someone with vagcom leads it is worth checking the logs to see if there are any faults. Alternatively take it back to where you had it mapped or depending on where you are based you can pop it to me and I can give it a quick check for you for free.
