XRT pro mild tune and 2000 rpm at 55

[bushman134]

This doesn't seem normal. Should be at around 1400 rpm's at 55. Also doesn't shift into overdrive till 60. Not gonna help my mileage any for sure. XRT pro is upgraded to the latest the 6.4.4

Engine RPM VS Road speed is dependent upon the current transmission gear. Try some of the new custom transmission downloads to find one that better suits your needs.

They just came out with another downlod 6.4.5. They also have custom tuning for the tranny. As soon as i get off the rig in may im trying this out im interested to see what a difference it makes

Thanks H&S Tech you guys are the best. I will post here how it goes. Thanks again

Loaded the 6.4.5 update on the xrt pro and loaded the S1L on also Installed the tune (mild) and now have a CEL (P06039) also can't change to wild or hot stays in mild. Any help appreciated

[H&S Tech]

Can you get that DTC for me once again. P06039 is not a valid DTC.

Did you notice the difference in shifting VS the previous version you had run? (just trying to verify that the download got installed)

Also, why wont it let you change power levels? What does it do when you try to?

DTC is P0603 When i change power levels it appears to do so beeps etc but when i look at what is loaded it stays at the mild tune ??????

Yes, the Mild tune description inside the show settings screen refers to the tuning family, ie HOT Damn, or Mild.

So it sounds like you may just be having a PCM problem.

I have got your email and we will work with you from there. Thanks!

Thanks. With H&S help I am back running and they are working with me. I would not use any other tuner and files and will recommend them to anyone asking. H&S response to customer concerns is fantastic
