Alright, posted this on the HPTuners forum, but got zilch for replies. My truck thinks it has a 27.49" tire on it. It really has 30's. Go to make the change in HPT and it will not let me click commit. Under current size it has "error."

I've attached my tune

 

Here you go, I went in and manually changed the VSS pulses per mile and Trans rev per mile tables for a 29.8" tire and 3.23 gears.

 

That will work but its still weird. I haven't seen that happen before. Have you emailed support at HPT? They'll fix you up.

 

how much are you spraying with 24*?

 

Thank you, appreciate it.

Got an e-mail off to support today, see what happens of it.

On this tune, not spraying it. Although I'd be perfectly comfortable spraying a 100 on it. Average IAT's this time of the year for me are around 45 degrees. I can run some decent timing. When the truck was a 4.3, I sprayed a 150 on it on 26 degrees.

 

Let us know how it turns out.

 

Didn't I tell you Devin? VSS PPM.
