The Beaudesert 3"exhaust and Steinbauer module went in last Friday and the difference is unbelievable. Because both went in at the same time, I don't know where to apportion the greatest credit. What I can say without getting technical, is that the immediate power when accelerating is brilliant, fuel consumption pulling the 30foot van seems improved and towing ability is much better with much less gear change. The fitter ran out of time so the pyro will be finished off this week. The Patrol temp gauge held tight where it always does, the engine did not appear over worked at all and there was no hint of smoke (which I was warned to expect). I looked into these mods very carefully given that the Patrol is only a few months old. I am confident I have made a good investment for the trip around Oz.
