Yes I think you'll find after a Stage 1 map, you will burn some more juice, purely given the addictive thrust of a Stg1 car.
Goodness only knows how many times I've had to take the long way home recently. Car was mapped in December.
My Ed30 with Autotech high flow fuel pump, Dbilas Induction kit and Milltek downpipe/catalyst with a stage 1 Revo map is just fab. Good fun too..
