Can anyone help
Been a while since I had a Mini, and finally bought a new 2022 Mini S.
I have a question when it comes to tire size and the speed-o. The car came with the 205/45R17 tires and I noticed when checking the speed-o verses a GPS speed, the car is 3 miles per hour slower than the GPS. I have a full size Dodge truck that I can use a Smarty tuner and change the tire size where the car and the GPS are the same speed. (yes, I'm a stickler on things like this)
Is there a tuner or chip out there that i can adjust my new Mini in the same manner ?

You can use Bimmercode and an OBD adapter to set the speedo to the accurate speed. You can also make other tweaks, like starting in sport mode by default, turning off the nav warning when you start the car, folding the mirrors automatically when you lock, etc.

First off, it’s by design that the speedometer reads slightly lower than actual. European regulations say that the Speedo cannot read less than actual, so in order to account for sensor tolerances it reads slightly high.
In coding the vehicle, there is no setting to adjust to tire size, but rather to have the speedometer display the actual reported speed, instead of the “corrected” speed. My suggestion is to just leave it, and step up in tire size to a 215/45-17, which will help with speedometer accuracy and also give better handling.
In my opinion, there really is no need to be that concerned with actual speedometer display., especially when the car doesn’t even have a dipstick….

Interesting read, the speedo on my 1995 Subaru Legacy wagon (I've owned it for 24 of its about-to-be 27 years on the planet) similarly "reads high" -- which I noted as compared to those radar-based "YOUR SPEED IS" signs posted on side streets form time to time, not as compared to GPS or the like. When GPS speed measurement got common enough, the discrepancy was identical.
I ultimately replaced my Subie's speedo (with my own two hands) and guess what? No change. Which served for me as confirmation that the variance was either by design or due to technological limitations. I believe I also noticed that the speedo got "closer to actual" as you got faster, but I forget the top-out point (maybe 75MPH, been a while so not sure).
Anyway, seeing this discussion in re the MINI (I have a 2017 F56) is interesting and I definitely appreciate the explanation about European requirements. Thanks @njaremka !

It reads slightly lower...it reads slightly high....huh??? Which one is it?

It should have read that your speedometer will read slightly higher than actual space-time speed due to the European standards. So if your actual speed is 60mph, your speedometer will display 63-ish. However, reading the first post again, I’d be tempted to think that OP has an inconsistent gps device…
