I think that the 85hp tune is the best for fuel mileage for me. I have not gone through a whole tank of fuel yet so I'm not sure

yeah well after the tranny got settled down and took some time to relearn the new power it stopped smoking completely.

What are you guys plugging in the predator to get the tire size correct. I got 285-75-16 and i will plug that in and its still a little off according to my gps.

Just wanted to see what everyone else is using for their 285-75-16.

Thanks.

its got 28K miles on it. I still am babying it bc the tranny has not had time to adjust yet.

I just bumped up my predator on the 120HP tune for the first time and all i can say it WOW!!! SMOKE, SMOKE, SMOKE!!!

Obviously i am still letting the transmission relearn so i have not got on it what so ever and it is putting out some serious smoke! I have not even given the truck a solid 1/4 ...

Ok cool
Thanks!

My turbo vane positioning sensor went out a few months ago and returned it back to stock and they didnt say anything about it. What does the new software have to do with taking it to the dealer? Is it because they can detect that i had it hooked up? And by the way i have to take my truck in to the ...

Ok ill try that, thanks!

My predator is the V.8r20 Is there any new updates that would require me to update my predator? I have never updated it since i have had it. Also i have a Mac, can u use the software for the predator on a mac?

I do a lot of highway driving and i need the best fuel mileage possible. Just wanted to see everyones opinion on what HP setting everyone is getting the best MPG on the highway and around town. I am currently running it on the 85HP setting now.

The only mods i have is a ready lift leveling kit ...

What revision is that?
