I only bought mine a couple of months ago so no idea other than a remap might kill off any flat spots.

Are the conditions when the car flatspots reproducable at will? If so, what are they?

no just happans when ever lol starting to do my head in now

dont no if this helps but i cant get the mpg up past 22.7 even if i drive like a grandad
