Remaining Distance very innacurate?

I had thought that the DTUK 'economy' box I put on my Yeti was the reason it was occasionally 'surging' under certain conditions eg @ 90kph on dead flat and straight roads the tacho would occasionally jump around between 1700 and 1800 rpm....I now think the very specific 'economy' driving style was activating bursts of 'emmissions testing bypass' programming as the DTUK supplier had never heard of such behaviour from their 'box' from other owners.
The actual economy figures didn't seem to alter much but when provoked it certainly gave at least 125 type power from the 103.

Those sorts of economy boxes are marketed with that name so you can more easily justify expenditure to the wife (or oneself). I think it's really about the powaaa

There was the choice of a 'power' one but I chose the economy one and still got predominantly (only?) power.
I think each time it 'surged' it went into polluting mode and when cc overrode it it went into 'fake' mode and so on and on ......
