Maybe i'm just an immature middle aged whoever...but I thought that was funny ~ I needed a laugh today and that was it....

 

Isn't there some type of "free refill" period?

NICE!! Getting the 310 tune?

As long as its stock when it goes to the dealer, he's under warranty.

 

I was actually considering the 275 tune.

Yes, that's true. As long as I put the DPF/cat back on and reflash the ECM to stock, I should not have any problems. I have a very "understanding" dealer who even sells tuners, so I am not too worried. I just need to come up with another $500 and I will be ordering it. I've got some OT scheduled this weekend, so we'll see.

 

I dunno, but for 85 bucks I'll pee in the tank.

 

last truck i saw that had the dpf delete and chipped truck completly blew up an injector and grenaded the engine...just a heads up

 

Yeah, that was why I was looking at the the 275 tune and not the 310 tune. I currently have the Superchips Flashpaq performance tune installed, which adds about 80 HP and 125 lb-ft of torque. I'm just afraid that running it with the DPF on there is going to clog it up. Since I got the truck last year, I have been running the tuner for three months, then taking it off and running a tank of fuel with the truck set to stock. It's funny because the truck actually gets better fuel mileage with the truck tuned to performance that it does with the stock tune.

It also goes into regen more often and the turbo spools up to 40 lbs almost instantly with the performance tune!

 

Anyone care to explain to me how this new urea system works? I am a little confused...

 

There is lots of information online...here's a start for you.

Wiki on Urea Injection

 

And yes - urea is made from urine.

 

From wikipedia:

So, I guess you could distill your own **** to remove the 95% water and the other impurities and make your own urea. Good luck with that!

It reminds me of Kevin Costner in Water World.

 

Urea in its natural form is in urine, but what you burn in your truck is a far departure from it. The urea that is used for emissions, also called DEF (Diesel Emissions Fluid) is a 32.5% urea solution in de-ionized water. You have to use de-ionized water as the mineral and other impurities in regular tap water will wreak havoc on the injector and the dosing unit. The other down side to urea is that all parts have to be plastic or stainless steel as its very corrosive. Luckily it does not deteriorate plastic/rubber/painted/sealed surfaces. The diesel exhaust smells completely different when using this. Based on my first hand experience with a urea injection system the fuel economy should go up under a lighter load vs a Tier 3/4a system, but under heavy load the economy will probably be close to the same.


When I kept hearing the refill interval I kept thinking that it sounded awefully high, but after running the math tonight I guess its pretty close to right.

Just estimating an average of 20mpg in 15k mi thats about 750 gallons of fuel. The last I checked AdBlue (DEF/urea) was around $4.30/gal, and for 85 gallons thats about 20 gallons. The 20 gallons of AdBlue to 750 gallons of diesel is a tad under a 3% ratio fuel/DEF which is right in the 3-4% ballpark for Tier 4b. My numbers might be a little off since I was just guessing at the 20mpg.

I can tell you that urea sucks to work with. It crystalizes on everything when it dries out, stinks like you wouldn't believe (ammonia), stings like crazy when you get it in an open cut, and I can tell you from first hand experience it DOESN'T taste good at all.

 

My buddy has a DPF Delete on his 08, preety cool smokes a bit now but he still gets only 10 MPG. He has an 08 CC ShortBed 4X4 - 20" Lexani - 35" Nitto TG's - 2" leveling kit

He gets better on stock tune with his SCT. They are preety peppy with a chip, but he pulls one leggers all day long.

 

Why can't they just leave the diesel engine alone? Rudolf diesel never intended diesel engines to be fuel hogging...

 

Ole Rudy also didn't have to deal with emissions laws. Give technology some more time - I'm sure you old timers remember when emissions laws first came into effect for gassers and how bad they ran and how bad the mileage was.
