Pretty accurate according to both my dash cam and GPS MPH readouts.
AlfaOBD would’ve been great but I don’t have/use any Android products.
Thank you for being the only person to actually respond to my original question!

I’m my post. “Tested MPH via Waze. Dead accurate”. Your speed won’t be off that much with just 33s”. Maybe 4-5 mph at highest speeds and a couple around town. It’s worth it especially if going to AT tires.

I called four dealerships (Richmond, VA) and none of them can (or are willing to) recalibrate my speedometer. Should they be able to do this and just need some convincing? Or do I need to go an aftermarket route?

I had mine recalibrated at my dealer. Called before and they told me they can do it for $150. I went to 295/65r20 and my speed is now pretty perfectly matched, and same for my gas mileage.

My dealer offered to recalibrate mine for $150, but I was already buying AlfaOBD so I declined.

I think those dealerships are just being lazy. IMO, you're better off doing it yourself. You'll save a few $$ and have the ability to enable other features if you want.

Agreed, this is the route I am going as well.

Anyone in Norcal have an AlfaOBD thats willing to recalibrate my 20 limited? I went from Oem 22's to 35X12.5R20

Edit: I decided to go the Dealership route but the Local Dodge/Ram Dealers around me are saying that its not even possible! mind blowing. Does anyone In Norcal or even Socal Know of a dealer that is willing to do the calibration?

I'm iOS too, and went with the Jscan.

The reviews on Jscan seem pretty good. You used it to change tire size? Any issues
No issues but it doesn't have all the extras that Aplha does. I changed my tire size to 33".
