Do chips help mpg, egt's ?

I did a test to see what the difference was on the different setting's on my chip. Stock, 40 Tow, 80 Econo, 120 Race. My neighbor owns an 04 Dodge Cummins and was wondering if a chip would help lower his EGT'S he runs 1250 degrees, empty at 65 mph going up this grade by our house its 7% incline and about 2 mi. long. This is what I came out with at 65 mph.

Stock:
EGT 850
BST 24
TRANS 120
RPM 2500

40 Tow:
EGT 825
BST 12 Half of stock
TRANS 120-140
RPM 1750 Huge difference over stock

80 Econo:
EGT 820
BST 12
TRANS 140
RPM 1750

120 Race:
EGT 820
BST 11-12
TRANS 140
RPM 1700

In my opinion it ran more efficiently, less rpm's, less boost, and slightly less egt's than stock there by saving fuel. I plan to do this again pulling my 10k trailer. I did this for my info only and would appreciate any input or comments.

Generally the best way to lower egt's is to open up your intake and go with a larger exhaust. I don't know much about the Dodge cummings trucks. Usually when you add a chip it adds more fuel therfore higher egt's, but your test seems to throw that out the window

Well actually looking at you numbers now you are running those egt's at a lower rpm then stock you would have to run the truck up to 2500 rpms with your different settings and see what your egt's would be.

I thought the test showed that with the chip it required less effort (ie. rpms) 2500 VS. 1750 to maintain 65 mph there by using less fuel.

Your RPM's will be the same at a given speed. IE:2000rpms = 70mph.

Might as well chip it though

Not if your truck has to stay in a lower gear to maintain the speed. Less throttle position which means less load, which means less boost, means better MPG.

They seem to run just about the same if not a little bit warmer. Mine will barely get to 1000 in the stock position with a stock intake and straight pipe andd with a tuner it hit about 1250. I put a TST box on and it would go over 1400, but now I have a really hard time getting it over 1200 since I put on the bigger turbo.

The truck has 4 speed auto incl. overdrive. In the stock setting it had to downshift to 3rd in order to maintain 65mph raising rpm's using more fuel. On level hwy I would agree with you Maintain about the speed but, if I had been trying to hold rpm's and not speed I would have been going verrry fast in the 80, and 120 mode. What I gather from the poll response is some chip's are better than others but, with a good chip you will improve performance and not sacrafice milage. I have seen my mileage improve 2-3 mpg since installing mine and I check it at the pump.

I depends on the driver more than the chip, but you need a good chip.
