We have all of them and the 05 is the worst of the bunch it has the same exhaust and chip as the 04 and also has a egr block off plate and no cat because the egt were way high when towing. it got better but 4mpg less than the lb7. lbz is a great set up. Can u put a lbz computer on a 05 lly truck?
the lly gets the worst mileage of all the duramaxs only was in 04.5 -05 trucks the earlier lb7 didnt have the emmisions the lly was the first smog motor then 06 got the lbz and does much better.
I was watching the World's Most Expensive rides I had tivo'ed with the Mercedes boat and was wondering why an oil change on that car cost "$10,000.00"?
Not to start a never ending war but 3 times in Fountains have won first overall in races and ANY race fan has to admit that the OLD Rio Roses 42 kicked ass and Cat Killer even though it has engine gremlins it eats up rough water. There were some BIG cat racers that said that boat carried the mail.
