I fitted the Tunit as soon as I got it (on time as promised) I then headed off on my scheduled trip to Wales. I notice immediate improvements to smoothness and engine sound. It has changed many detailed driving changes to many to identify at this time but two stand out: Several times I thought I was in forth when I was in sixth due to improved torque and an approx 10% gain in fuel economy but that is only one trip and less than a tank of fuel. Thanx for your help.
