I run a Hypertech stage 2 tune on my 2004.5 Cummins when pulling and I can definitely feel and tell a difference while pulling. When I am running around town and not towing I run a stage 3 tune on it and then go light on the accelerator for a 4+ mpg increase in fuel economy.

I also have a 5" custom exhaust and have mild tranny work done to my truck (increased tranny pressure with new valve body and solenoids) and it has 134,000 miles on it with the orginal tranny in it and is still going strong. I will say this if you are going to tune a diesel you MUST have an EGT gauge on it so you can monitor the exhaust gas temperature as every truck seems to respond to a tune a bit differently depending on injector spray pattern, exhaust flow, etc......

Thanks for the replies. It's a 7.3 and everyone I know are always saying I wish I had never traded my 7.3 ...... Couple recommends on the Hypertech so I think I'm going to try one. Heck I spend that much on coffee in a month. If I don't like it I can go back to stock and put the Hypertech on the shelf in the shop.

The 7.3, 6.0 and 6.4 can all benefit from programmers. Then it's just a matter of how you drive it and the upgrades you put in along side the tune.

I don't personally have experience with the 7.3, but they seem pretty reliable out of the box and can handle a tune without too much need of anything else.

My previous 6.0, I did an egr delete, turbo back exhaust, intake and SCT X3 tuner. The tuner made better use of the upgrades with the programming and resulted in better MPG(16 before, 19 after) AND more HP. I wasn't trying to race anywhere, so lifting the heads and blowing gaskets was never a problem. I would never want to leave a 6.0 stock, as too many stock parts cause it to fail.

6.4's benefit even more from programmers as they can turn off the computer's regen system and when coupled with a DPF/Cat Delete exhaust along with an EGR Delete have show great improvements in both MPG and HP.

You definitely have to pay to play, but done right, programmers (in conjunction with other mods when needed) can be very helpful.

Most of the people that come in the dealership want to "stud" and "delete" their 6.0's. Although, legally we can't do it. We recommend another shop due to liability. But the changes are dramatic.

Some quiet reading for you to research chips and what will work best FOR YOU and YOUR GOALS.

As for tuners versus chips Tunes you can not switch tunes on the fly you also will be limited to generic tunes or only one maybe two custom tuners and then you will be very limited in your choice again. In just about every way the chip is better choice. One thing that can be of confusion on here if you are somewhat new is the use of the term "tuner". On here we are almost never referring to the device called a "tuner" but the person that actually is writing the tunes themselves for the chips.

I would say, easily, 99%+ of members on here and most other dedicated 7.3 sites use a chip not a tuner.

One other thing to keep in mind: the maker of the popular chip used by many tuners to installed there tunes on is the "TS chip" )6 position chip). But that same manf also sell that chip with generic tunes directly to the public as well. So you will see comments about "TS style chips" from one of the custom tuners you are about to learn about with some reading. You want the ones from the custom tuners not the generic TS chip and tunes directly from TS or others. You will quickly understand the difference with some reading.

Of the various custom tuners out there these are the poplar ones with the best reps. Read the thread links below to learn more about them to help you make your choice:

Custom Tuners:

Gearhead Automotive (Matt)

Beans (Jonathan)

BTS (Cale)

Power Hungry Performance (Bill)

Diesel Innovations (David)

Total Diesel Performance(Tony TW)

Truck Source Diesel

DP Tuner(Jody)
I did a lot of research before I bought a custom tune ts6 for my 7.3.
Several things I was told was first get to breath in and out, intake and exhaust. second get gauges to watch temp and boost. Third put the chip in. I did all the work myself and was pretty simple. This has been three years ago and I wish I would have done it sooner.

I have a programmer on my 6.7 cummins. I also did a DPF delete and EGR delete. My empty mileage went up to 22 mpg on the hwy. on a 5 hour trip towing our trailer thru the mountains we averaged 13 mpg. My truck averaged 15 mpg on the hwy before and 12 towing.

2010 post by Tram on Power Stroke Nation and most of the links do not work. The sites that do seem to be geared to high performance (race) The 7.3 does not have EGR or DPF so no delete options. I'm looking for a simple chip/program for towing power gain. If the "program" works it will likely be there if I ever sell as the primary use is towing, I have a GMC 5.3 for daily driving.

Programer came in and tow program installed. About 100 miles empty but it is more responsive, idles smother, and seems quieter warming and driving. Off in the AM for about a 400 mile trip with the camper. I'll check mileage when I get home.

Ive had a programmer on my 7.3 since day 1. Its got almost 200k miles on it without any engine trouble at all. I get 17mpg empty on the interstate, pretty good I think for the gear ratio in the 4 speed 4r100 tranny and a 3.73 rear gear. I get 11-13 towing, depending on the weight and conditions.

I did have to put a transmission in my truck at 170k miles. I've read they were the weak link in these trucks even stock. I've also pulled a lot more weight with mine than I should have from time to time in the past so im sure that contributed to the cause.

I'm not sure NM has any flat roads it's all mountains. Been a couple weeks and a couple trips. It looks like MPG is holding in mid 11's but definitely more power & less down shifts pulling grades.
