Why are the tuned 7.3's more desireable??

Not to mention the mpg that can be coaxed out of them with very little effort. I'm 48 hrs from my DP and my mpg experiment. I'm going down 232 miles with my Superchip and back the same 232 with a brand new DP, I will post the results and not compromise the test in any way.

I'll be interested to see how your experiment turns out.

Mark, this is exactly why I have kept the 330 hypermax chip the truck had in it when I bought it - my truck gets excellent mileage, even with the lift and bigger tires. On an easy highway trip, keeping the R's down, no hauling, it's been know to get 22mpg.

A friend of mine has an 04 6.o and ran the snot out of it with no problems. He once told me he was getting 600HP out of it with a straight pipe, intake, and the Edge. I told him not a chance, and if thats true then I am pushing 450hp. He swore up and down that I am reading to much crap on this site and its filling my head. But another guy with an 03 6.o had nothing but problems. Nice truck, wrong powerplant. Then another guy I know has 325,000 miles on his early 99 and not a lick of problems other then a water pump.
LONG LIVE THE 7.3

The superchip does seem to had a hard shift to it. If what you said is true I am tuning mine back to stock. I don't have money for a new BTS yet

I ran superchip for 4 years with nothing but a muffler delete pipe pulling the heavy loads. It didn't hurt anything but my feelings once I got the DP. Such a difference. I would change programs as needed with the superchip. Some people put it in performance and never change it for towing. That will hurt your trans.

I believe he is refuring to his piston rods. The 01, 02, and 03 model 7.3's came with PMR rods (crappy and easy to break when running high HP). Guys with HP over 400 are encouraged to replace these crappy piston rods with rods built to withstand the forces of higher HP. SS sticks is his slang for stainless steel rods.

SS sticks = Single shot injectors (sticks)
Stock injectors apparently injects a "pilot" shot of fuel, then the "body" shot of fuel.
These stock injectors can be replaced with SS injectors which cause the motor to run a little louder, but apparently more fuel efficent and more power.. I do believe most of the serious hot rodders use SS injectors.

"SS Sticks" = Single Shot Injectors. Single shots inject more fuel with less oil, so you can get a good HP gain without needing to go to big oil (High-output HPOP). BUT they require custom tuning in our trucks because the stock injectors are Split Shots. And to fully take advantage of the extra fuel, a larger turbo is needed as well (at least a van turbo/1.0 exhaust housing).

I just dropped a set of (small 175/146) Swamps injectors in my truck. Man, those coupled with DP Tuner makes her fly compared to my old Predator, never mind the difference between stock! I will absolutely concur with the fact you should get a bigger turbo. I make a lot of smoke when I want, but I'm sure if there was more air thrown in the mix, I'd be putting more power to the ground, instead of in the cab of the ricer next to me!

7.3's
If I may chime in:
I recently bought my first truck with a diesel motor. But I have been driving vehicles on a regular basis with Powerstroke motors since they were introduced. I still remember our first ambulance at work with the PSD. Compared to the older 7.3's, that thing was a rocket. And we never had any trouble with them.
As our fleet is constantly evolving, I have driven every year Ford with a PSD. We never had any trouble with the 7.3's. But the 6.0's were constantly out of service and in the shop. One of the 2006 ambulances we have is on it's 3rd complete motor. It has less than 30,000 miles. Turbos are constantly going out. Head gaskets. Fuel problems. Electrical issues. Cooling issues.
And that first 7.3 PSD ambulance we had, it is still in service with another jurisdiction. And still on it's original motor with over 150,000 hard miles.
So when I was in the market for a F-350, I didn't even bother looking at a truck with a 6.0...

Goodness Asystole! You really brought this thread back from the dead...
Yep worked as a fire dept medic for over 34 years, was witness to the multiple fleet changes during That time. The 7.3's ruled, running 24/7, long idle time to ***** to the wall's running flat out on the streets and surrounding highways, not to mention in the coldest and hottest of weather. Occasionally starting or charging issue but what do you want for running like mules.
