Change your air filter and PCV, clean the EGR. You might as well change your fuel and oil filters while you are at it and use 5w/40 fully synth oil. Check your tyre pressures (and that the brakes are not dragging)
But what 'tuning box' have you ordered? A faulty MAF can cause fuel consumption issues but for resolving issues with them anything other than one of Rover Ron's Synergy boxes is dubious at best.
And do a search for setting the trip computer, I recall there is a thread somewhere about how to adjust it so that you get a reading closer to your actual fuel consumption. Worth remembering the trip computer is just a computer - and 'garbage in equals garbage out'. There is no point in believing an instrument that is not error corrected.
