:agree: Yea, what he said...
I own the same truck, only a King Ranch... 07 KR CrewCab, Dually, LWB 4x4..
I have owned an 06, same truck... Had a little lapse of sense and went to a Silverado for 8 months, but it was doing R&D for the Owners towing our off-road trailers at Bushtracker, as it is a nice luxury car, but I love the feeling of a tough truck... And now I am back home... :icon_ford: No problems with either Fords...
From a couple of years of research, and seeing 20 of the 6.0s running here towing Bushtrackers, he is pretty much right on... That can in front of the exhaust is the Cat.. I punched mine out on the 06, sounds a bit better but did not notice much else from it...
After trying a SuperChips on my 7.3, Edge Platinum with Attitude on my 06 KR, and Quadzilla on my Silverado.... I have just ordered SCT Xcal3/Livewire And an EGT Probe... And I am looking to increase the exhaust to say 4", maybe 3.5 downtube to 4" exhaust.. This is all geared to maximum fuel economy for really remote areas....
All of this is for extreme towing in one of the most remote places on earth. With my research, all 120 of these 6.0s converted to right hand drive here in Australia, there is a 5-8% chance of blowing a Head Gasket or EGR Cooler... It is hard to base a judgement on such a small number of trucks, but it is an indication. Most of those that had problems would be chipped up trucks, and I will stay on Economy Mode ... If I can organize it, I am planning a Cab off Head Stud job and EGR Blockoff. For you? I would say don't bother unless you are into Tractor Pulls or Street Rodding.. Odds are in your favour of not needing it by 95%
I may do it, but that is because the cost of a breakdown way out west, might be thousands of kilometres of recovery, MORE than the cost of the engine upgrade... For you, a Dealer or repair is right around the corner, for us here it is remote to none. Hense the great deal of research I do both in Australia and on this wonderful Forum...
Also, my research is extensive, because my King Ranch cost $120,000 here in Oz... :yikes: Right now that is about $95,000 U.S. and when I bought it was about $110,000 U.S... Got to love your Ford if you pay that kind of money! Luxury tax of about 10k, import duty, 10k in shipping, 30,000 for conversion to new dash, new steering, firewall and all the rest.... You bloody well have to care a lot when you fork out that kind of dough. I think my research and advice is correct, because the statistics are about the same on the trucks from Oz to America... :thumb:
