so if lets say its had a stage 2,is this putting massive strain on the turbo? and what mpg should i be averaging,same as stock?? and roughly what bhp are we talking? i was happy with it being 180 standard, dont get me wrong i like the acceleration when i put my foot down but mpg bothers me,and im not made of money and all this remaping etc will it cause me to be spending extra money keeping the engine in working order.is it easy to unmap?
