The truck does have the O/D Off mode also, it comes on when I hit the tow/haul button twice, and I still have the filter, or cataletic converter, or resonator, not sure what to call it. And its going back in due to the California smog law, and I think im just going to leave it in full time now, its a hassle to keep taking it in and out. But before the law went into effect, doing a bigger exhaust system, and allowing the exhaust to get out quicker, or to let it be cooler, seemed to be the thing to do on the diesels back when I bought the truck in 06.
Bigger Exhausts are great for Diesels as they are basically big air pumps... so the more air out the better... but you also have to be able to get as much air IN as you do OUT... a 5" exhaust is pretty large without putting a tune on there....
I think a tune would definitely help you.
How heavy is the load you're hauling?
