I have the U7165 with 5 or so crom files and I was wanting to see what you all think is the best file for mileage, I am running the most current and getting 17mpg.

All will be about the same. I have heard alot of customer say the 65hp tune works best.

The 65hp Economy Performance Tune is what you would use. Unless the name changed. Post the list of names of the available tunes.

I have 9r04, 10, 11, 12, and 14 crom files. I was loading all these crom files thinking they get me where I wanted to be yet I found out I had egr cooler problems, oil cooler and hpop issues and since those have been fixed my truck runs great. I am happy with the 9r14 but I was just curious which crom file was the best.

Thanks for the tip but should my tuner come with tune or do I need to install it (65hp economy tune) because it is not one of the current options?
