Ok. I have the TST PM 3. I run it on 4 most of the time when running around back roads. When I get on the <br>interstate, I run it on 9. Why? Well I have found that I get awesome fuel mileage when at this level. How? Well you tell me.<br><br>I am getting ready to run to Virginia in June to see Dieseldude 4x4. Between 8 and 10 hours of driving.<br><br>I was wondering if it was ok to leave it set on 9 for the trip. May be a stupid question, but the only stupid question, is <br>the one not asked.<br><br>Thanks.

If your EGTs are under control and your fuel pressure is good, run it at 9 all day long if you want. Both Scotty's and my own truck's fueling boxes rarely come off the highest level.<br><br>Rod

Cool. Yes my egts are great I think around 900 until I mash it, but steady 75 and 80 they are great.<br>Thanks for the info.

Yep, I run mine on 9 all the time, too ;D
