I have not installed a rail pressure guage yet. I just tried a few settings that I like and have made note of what others have seen for pressure. I need to get one to help dial in the settings for the truck. My next group of mods will include a rail guage. I would like to use a typical guage by Diprocal but have heard some people were having troubl;e with them. The other digital guage is just not going to find a convenient place to call it home. I have my TST on the steering column in the location I have seen many users put the digital rail guage.

 

From Killeen, Tx to Weatherford, Tx last night I averaged 19.77 MPG hand calculated. 160 miles interstate at 2k rpm at about 67 mph. And the rest country road and city driving regular, blowing a little smoke at the other diesels around here.

With 4:10's and stock height tires 235/80/17's, I was extremely happy about that. Considering my last truck never broke 16 hand calc with the Quad MMM and 35's and 4:10's on the interstate no matter how conservative I drove. And I just got my Valair 3850 DD this morning. Can't wait to put it in.
