So for us guys with 2011's , how do we recalibrate the speedo when upgrading to larger tires (example.. 255's to a 35" tire) since there is no tuners available?

Only option is the dealership...thats what I had to do unfortunately

 

Wrong, and get a Procal mine works perfectly.

 

I heard that the dealership could only recalibrate to a 32" tire. True or false?

I thought they didn't have a tune for the 2011's.... What else can the procal change?

ProCal worked on mine.

I changed the tire size as well as turn off the TMPS light. I'm not running the TMPS sensors in my new wheels/tires.

 

I was also wrong on another note, superchips now stated you can now use the tire setting and pressure setting option but still no tuning for the engine.

 

The AEV Procal will let you change run every option it has listed on a 2011. I have gone through all of them on mine and they work flawlessly. Set my tires, gears, running lights, enine idle rpm's up for winching, clear codes, etc..

The AEV Procal is not for tuning though, and superchips is not up to date yet with its tuning for the 2011+, that's why I sold mine and picked up a Procal from Northridge.

 

So you WERE able to adjust tire size greater than 32" ?
