thats what i was thinkingit says it increases fuel to the engine yet it still gives better fuel consumption ? hmm More Fuel More MPG, sounds like when you go to the pumps and put 30 quid in you got wife as far as when you put 15 in
it fools ecu into thinking the car is cold, and hence runs on the 'cold' map - waste of time and money, and will bugger your engine in the long term + will loose you power - makes me sick they can make such claims and get away with it
