But for a long unloaded trip, such as the 350 miles to Dallas on I-20, I'd switch to 80-economy.ģ. 80-economy, even though I didn't use it much. 80-tow for trailer less than 8,000 pounds or less, or 60 tow for trailer of 8,000 to 10,000 pounds.Ģ. If I were going to install a chip today, I'd go with the plain DP-Tuner multi-position chip and have at least 4 tunes with a tune-switcher that DP-Tuner sells.ġ. I had a separate exhaust brake, which is required in hills or mountains. I also had 80-economy but it didn't seem to offer any advantages over 80-tow, so I usually just left it in 80-tow all the time. 80-tow was perfect for towing my 8,000-pound 5er on the flats or in the hills and mountains. Let me know if you have any other questions.Back when I still had my 7.3L, I had DP-Tuner tunes in an Edge programmer. You can find all of that information HERE. If you buy the injectors elsewhere, then you will just have to pay the custom tune fee. If you buy the injectors through us, then we will update all of your tunes for free. We suggest adding transmission,fuel and stronger HPOP modifications to see the full benefit of this program. The 140 aggressive has more fueling than the 140 extreme in the lower RPM range for stronger out of whole power. If your truck smokes excessively for more then a few seconds you have low boost pressure issues and or low oil pressure issues. With a diesel, all tunes smoke if you stomp the throttle hard, even stock until the turbo spools up and clears the smoke. There is no benefit to excessive smoke, and it just puts a bad name on the diesel industry.

That is correct, we do not offer a smoke tune anymore. The mileage gains will be about the same with both tunes. I actually like running the 60E better on my truck though, especially for city driving. Most opt to go with the 80E because it offers a little more power than the 60E. The 60E and 80E are both great for daily driving. A tune may help a little, but most people do not see HUGE mileage gains.
