AFM Failure - Weak mixture on boost
Looking at previous threads on the topic I got the impression that a faulty AFM affected the idling/slow running. Beware that it can give a very weak mixture on boost with no other apparent symptoms. Idle and general running was smooth.
This was confirmed during my Tec3 remap (at Powerstation) last week and they had to fit a new one.
Could be nasty if you persist in booting it and don't notice the AFM reading (or don't have one). You should notice that performance feels weak though, also improved fuel consumption.

I forgot to mention this, the strange thing is I have a Knocklink and it showed virtually no activity (yes it is working, lots of activity before AFM went and some after replacement and remap). I would have thought weak mixture/overheating would have caused det?

After your new maf and remap you should have no knock activity. (by no knock I mean no more than green leds)
