Aev procal
This just dawned on me today. It has been highly suggested to me before that I need to buy the procal or other tuners to adjust my tire size (now running 305/70 r17). When I purchased my 2012 jk it had the pizza cutter wheels and tires and I bargained my way to have them upgraded my wheels and tires to the Sahara polished 7 spoke. My questions is the procal (or any other tuner) going to make a noticeable difference in anything other than my speedometer? I can't justify spending $150 to only get a more accurate speedometer. I'm assuming that my settings are most likely set to the stock pizza cutter settings if that helps.
ps. I will admit that I am not mechanically gifted at all and don't understand half of the really technical stuff on here, but I'm trying to absorb as much information as possible.

You prob just got an upgrades rim package but the tire it self is the same size. Once you go to 33" or 35" you would want to get a ProCal to fix the speedo. If you don't mind your speed being wrong then I guess you wouldn't really need it. But of you think 150$ is a lot to spend just wait until you want to do something else to your jeep...150$ item is jeep in the jeep world.

I have an 07 JKU Sahara with 4.10s. My avg highway mpgs was about 18mi/gal with stock wheels/tires. I upgraded last week to Pro Comp MTs 35x12.5 on 15x10 PC 152s. My mpgs went down to about 13 highway. I bought a ProCal yesterday and tuned the ECU to the new tire size, and found that the JK is smoother and my mpgs are sitting about 16mi/gal highway. I think it will pay for itself in the next couple of months considering the price of gas these days. It certainly helps with shifting points as well, and can only benefit from that.

However, for factory wheels, I really don't think you're going to see much of a difference. The person above and myself run 35's which is a big difference over the stock wheels. When you compare a factory Sahara or Rubicon wheels to the base model wheels, it's really not that big of a jump.

Yeah, the 305's are roughly 33-34". You would definitely see a difference.
