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. Since then, we’ve replaced or rebuilt just about every component on it during the last three years.Back when I still had my 7.3L, I had DP-Tuner tunes in an Edge programmer. I bought the 12-valve as my first diesel when I was 17 years old. We’ve done all the work ourselves except for building up the 47RE. Both were bone-stock when we bought them, and we’ve put a ton of work into them together.
