My mileage is 18k a year about 60% town 40% motorway. I get 43 mpg but want more. My car has aircon that doesn't work and a cat. I have a K and N filter in the air box. Can I pull off the aircon pump and change the belt? If I decat it what difference will that make? Does anybody do a remap for mpg? I don't mind losing a bit of bhp. The car has done 142k and burns no oil. 1.36 on the smoke test.I would really welcome a bit of advice.
