Oh crud, this is Bill's thread. Maybe I should read the title before I go spouting off just because it's had a new post. I'm not posting any more in this thread, just the Bill vs. Cody thread.

I haven't had a chance to pull more than 9K lbs. since I've been home this year. I used to pull that kind of weight regularly back when I had a wife with horses......

That being said, I don't think that the truck would physically have any problems with that kind of weight, but I would absolutely NEED to get a different turbocharger or I would have to drive in 3rd gear. The surge is terrible above 9-10 PSI at 2000-2300 RPM and being under 10K lbs. keeps me at about 7-8 PSI on flat ground maintaining speed (picking nits, I know).

In addition, I'm being "bad" because of the 20" tires I'm using. They're not light truck tires and the sidewalls are a bit spongy....the weight rating is fine, but they're only load range "C" tires. The price we pay to look cool, I guess.

Anyhoo....

turbosuzuki has the right idea. If you want to USE your truck with anything above what stock injectors can give you, I would suggest a turbocharger and some increased transmission strength for reliability. We all know how much it sucks using a stock turbo with more fuel when towing and I have overcome the stock transmission's ability to "hold" when towing without cranking up the line pressure to insane levels.

Have a great one.
