Had an Rtech remap last week, on a 180mile 60% motorway run yesterday I got 57.1 MPG...very pleased with this. Just filled up with 75£ worth of V power...going to see what I get out of a tank of 'mixed' driving
I put near enough £70 week in normal fuel
You got the computer on the real time setting put it to the trip setting. I found its accurate to within 3-4% from when Ive worked it out in the past.Ive had over 650 miles from a tank and filled up before the light came on so another 55 miles till empty. Minimum I get is 550 and thats 80 ish on the motorway
