I had a suspect intermittent comms issue with the maf, managed to check today the dynamic values. Bit difficult on a busy d/c but found that up to about 5k was around 150, rising to a peak of 180 at just under 6k. From memory others are seeing more than this?

Don't have a log I'm afraid no facility to record the data.

Is it stage 1?

Yes, shark stage 1

In that case It's a little under what it should be.

This could be down to warm air. I wouldn't say it's really low.

I was expecting around 200 from what I have read elsewhere. No other problems with it, idle is pretty smooth, no misfiring, hesitancy, just seems to flatten out a bit at 5k which only appeared after the rocker cover was replaced.
