Oky, the 2nd tank of fuel went thru. Stats:
812km, 68lt. Equals 11.93 km/lt, 8.38l/100km, 33.7mpg. All highway, sitting on the speed limit, 70% 110kmh and 30% 100kmh. Still fully loaded. Now, is it getting better as we go, or just coincidence? Matt? The only downside is the fumes out the back, and a bit of black on a the paintwork immediately surrounding the tailpipes. I think I'll delete the rear mufflers and extend the pipes a little until I can afford to to the cat back system. We'll be towing a 2.4 tonne van ( that's loaded weight), so it will interesting to see the impact 700nm of torque has.
