I went over to SRD this morning for a remap on the navara, lee has built a few cars over the years for me and is a seriously clever guy, he looks after my other cars an all.
His workshop is down in West Sussex, 65 miles from my door, so I thought I'd test the mpg, on the way there I reset the mpg and averaged 31.6mph cruising at 70-80mph, after the remap I reset it again and on the same drive back I did 36.1mpg so was well happy with that.
Throttle response is loads better an all, picks up much quicker now, feels a little faster.
