That was kinda my fear when I bought my truck. My budget dictated that I could only afford a truck with a few miles on it so it would be cheaper. I have no doubt that a diesel would produce more power and better mileage, but what hapens when it's my wallet the diesel repairs are coming out of? It doesn't matter what brand of diesel we're talking about, my luck being what it is means I would inevitably buy one that had problems. But with the V10, I couldn't find any inherant problems AT ALL. Yes, the older ones occasionally pop a plug out (so does my buddies '97 Toyota BTW) and yes there's a possiblity the exhaust studs may give me problems, but other than that I honestly couldn't find anything. Hey, if I was gonna buy a new truck and could afford a diesel that I was only gonna keep a few years, I'd be all over it. But for me, I have to think long-term, and thinking long-term means what I can afford for the duration of the life of the truck. I don't know how the rest of the world takes a $20,000 hit in depreciation every few years, but I can't do it.

And I figure I save money every month driving the diesel over the v10 in gas alone, even after taking into account higher payment.

With big displacements, you don't need a lot of boost. Theoretically speaking, if you have 362BHP stock (3v V10), with 5 PSI of boost, you could be looking at as much as 485HP at the crank, which is pretty significant. Which sticks it right at round 350-380 RWHP.
With 10 PSI of boost on a V10, you'll be looking at the 600HP+ range.

Yeah, I don't know how some people buy new trucks every few years, snowmobiles every year, etc. I make a good salary with decent bonuses and had to buy a 2006 with 93000 miles. And I saved $4,000 by going with the 6.0. The duramax I really wanted was way too expensive. Though I did throw 2,000 into it for mods and repairs.

Now that's a perfect example of thinking it through! When I was looking for a truck online I saw TONS of fairly new trucks for sale, often with thousands in modifications, at huge losses. I saw one truck that claimed to have over $50,000 invested for sale for $18,000. The only thing that kept it out of my driveway was the 12" lift and 40" tires. It was a great looking truck with lots of high-dollar mods, though. The seller was in financial trouble and needed to sell the thing to pay off some bills. Sad. How do you recover from that? Anyway, for most people the mileage thing is definitely enough to warrant a serious look at a diesel. But for me, I live 8 miles from work and only tow a few times (less than 5) a year so the gasser made more sense. Since I was going with a gasser, I figured I may as well go with a big one, so with lower intitial prices the V10 worked for me.
So the argument of which is better for you, it depends on the use. Argument of which pulls harder, goes to PSD every day of the week! hehehe

Exactly, different strokes for different folks. I chose the diesel because I save about $70 every 1,000 miles in gas and I can go 240 miles on a tank. I drive about 1,500 miles a month, so makes sense. I also bought a cheap toy hauler that tows like a brick wall, rather than spend the money on an expensive toy hauler that is lighter.

Hmph, since I drove 5700 miles last month I saved a little over $350 in fuel cost? On average I save $280 each month? I wish it were true but the 6.4 only gets 8.5-10 when towing my trailer, which is behind me 95% of the time I drive. Even still, all that seat time I do appreciate towing with the diesel and won't go back to gas unless I have to, if it becomes too costly, which it may.

I would want to start with the waste gate set low and dyno tune it.
600HP + 20K = breaking something.
485 would be about the max for a reliable work truck, IMO.
I think with just the other mods and no turbo I would be making right about what a 3V does.
