That's what I'm hoping. I have set it to that. Will go for a ride here in a bit and see if that fixes it.

The range on the inTune Tire Circumference goes from 500-3510. And it looks like its set on 2319.

285/65-18.

Its the new Toyo Open Country A/T II that just came out. I don't see that information on their website.

When I go into settings it shows...
Application: 1r02c
FORD PID Db: 1r01a

2012 F150 5.0. inTune 1r01i.
Can someone help me figure out how to update my tire size. When I go in to the adjustments and tire size... It gives me circumference. I am used to the Predator and giving the tire label size. I went from 275/65-18 to 285/65-18. Nothing major, but I would like my speedo ...

Mine is an 2008 2500hd, 6.0, w/4.10. Id be curious to see if anyones tunes on the 6.0 are yielding better mpg. I am not expecting the world. But on a 2500hd, crewcab, longbed, 4x4 with 4.10's. Anything would help.

Subscribed. Would really love to have TCM Support.

I have been running 91 octane with the 93 Tune for a while now. I haven't really noticed any issues, but I haven't logged it yet either. So I assume I should go in and set my timing back 2* or 3*. Does anyone know if I would still see a difference with running the 91 octane as apposed to 87 octane ...

I am also a former SC Cortex user. I have a 2008 Silverado with the 5.3. I don't know of any exact numbers as my truck never sees a track. But I can definitely tell a difference between a SC tune and the Predator tune. I bought the Predator with the whole mind set of using it to change my tire sizes ...
