Hi Tony, Thanks for the 400R map and 650 injectors you done for me on thursday, the car is fantastic to drive, absolutly balistic !! Seems wierd but I done the same drive there and back ( not above 80 on the way to you and no traffic and the car used 3/4 of a tank of fuel and the trip meter said 90 miles to empty ). On the drive drive back home, again the same drive no traffic but with some higher speeds!! and the car only used 1/2 a tank of fuel??? The trip meter said 188 miles to empty??, the gauge was not stuck.So more Power and more economy from the Gabat Mapping !!Should have done it 12 months ago
