Advice on increasing fuel mileage...
So I picked up my first diesel truck last spring. 2005, 3500, 5.9. It has 80,000 miles on it, 4.10 rear end, 6 sp tranny.
I tow a skid-steer loader (9,000lbs tops w/ trailer) maybe 4 or 5 times each tank of fuel. Power is adequate and I get about 16 mpg I'd say.
I am interested in maybe an emission delete because I get the impression that these increase engine longevity and fuel economy. I have no idea the requisites for doing these mods, however, I am not concerned about warrantee issues. Could you guys please answer some basic questions for me?
-Does the 5.9 even have an EGR system? or is that just after '07 in the 6.7's?
-If not, does deleting the DPF make substantial mileage gains?
-Would I need to get a programmer after doing the deletes?
-What can I do to make the best mileage gains?
Thanks in advance.

You just have a catalytic converter and it is actually illegal to remove it. Tons of people have removed them including me. But emissions testing is non existant where I live for now.
The only thing I can suggest for you is possibly get a smarty jr. If you are getting 16mpg towing 9000 pounds I'd say leave it alone. Thats pretty awesome.

Driving style has a huge impact on mileage.
1. Slow down. My truck's mileage is directly dependant on speed. At 80mph I get 16-17. At 50mph I get 22-23.
2. Go light on the throttle. Watch the boost gauge during acceleration. More boost = more fuel burned. I get better mileage around town if I keep boost below 15 during acceleration.

keep your tires inflated. I run max tire rated on the front, minimum 60psi in the rear. More if I have a heavy load. As .Bob said, it's more driving style. Smarty Jr will help with increasing the timing. I wouldn't speed much more $$ on it since you're looking to increase your bottom line.

It doesn't save any money, either. You gain a little in fuel coss. But you wear out the tires faster, and increase your tire cost.

Not such a good idea. Overinflated tires decrease the contact patch and increase the wheel rate. It adversly affects handeling, ride, and braking.
It doesn't save any money, either. You gain a little in fuel coss. But you wear out the tires faster, and increase your tire cost.

the pay back to get rid of the in cylinder egr is a lot shorter than you think. get a pdr cam or call colt, hamilton or f1 and get a custom grind. get 35 hp nozzles and a smarty jr leave the smarty on economy setting. this combination will net 40% increase in mpg. how this works takes to long to print. but we have applied it to several and keep a record. this applies to the 04.5 to the 07.4 it also reduces soot loading of the oil by 75% reduces egt by 300* and gives more low end torque for towing
