Hi we just purchased a Nissan Note Ntec 1.4 having driven a nippy 1.6 Note for the last 12 years. Difference is pretty shocking and although the 1.4 is a 5 seater I am guessing the rear passangers are there to push the car up any sort of modest incline you might encounter. Can you remap these things to improve performance or are we just stuck with it. Just curious. 

You  might be able to get some sort of remap on it but doubt it will give huge amounts of power for the cost involved
