Difficult to say, because I only trust a full tank calculation, you know start off with a full tank and zero the trip meter, then when a decent amount of fuel has been used refill the tank and do the calc.
I did not get a chance to do this but did not notice increased consumption however I prefer fact to fiction!!
I had expected increased consumption after all conventional thinking is that these boxes just over fuel the engine and you do not get something for nothing, I am beinging to think that the boxes might be a little more clever than just foxing the engine into thinking that the outside air temp is -50 deg C.
I have just done a bit of Google research, it is difficult to see how these boxes are doing anything other than raising the fuel rail pressure, so this goes against my comment above, never the less it works.
