My vehicle was a sluggish mover but with the tunit fitted its a lot more nimble

Paul ,Toyota Avensis 2.0D-4D

Can now leave in gear on lower revs and reduce number of gear changes, also pulling smoothly throughout rev range ? Just need to fit new tyres on the front wheels to further improve mpg! Improved to 64.8mpg ? 16.5% better.
