Is it possible to go above 32 Amp charge rate when charging a 2023 Model RWD?

Short answer is no.
Longer answer is…EVSE is a not a charger; it’s a glorified/smart relay; it just controls the flow of AC power to the car. Chargers are actually onboard the car. As DownshiftDre mentioned, LR and Performance models have higher capacity chargers and can go above 32A. RWD models have smaller chargers and only deliver 32A.

At the risk of being pedantic,
RWD models have two 16A charging modules for 32A total (maximum). LR and Performance models have three 16A charging modules for 48A total (maximum).

I see it as adding more color to a painting.
I am in same situation, my M3 RWD , bought on 9/30/2023, only charges at home, thru the Wall Conntor, at 32 amps. My breaker is 50 amps and I set the Wall Connector for 40 amps.
Contacting Tesla tech support. Got confirmation that my M3 RWD only charges at 32 amps via Wall Connector. He also said there are other model 3 that charges at upto 48 amps ( as this post shows )
Oh well , now I know. At least, supercharging at Tesla station will be fast. Will have to try it soon. What surprised me is the saleswoman recommended me to buy the Wall Connector which can charges my M3 full in 6 hours. She should not say that !!!

On a 48 Amp station, I can charge my M3 LR to full in 5 minutes... if I start charging at 99%. Leave the second part away and you're looking at a correct but highly misleading statement.
As a rule of thumb, always challenge everything that sales people tell you. Or better yet, do your own research and bypass them altogether.

We have a MX Plaid and a M3 RWD. In my experience, the MX and M3 both recover from the same SOC in roughly the same amount of time, because the M3's battery is smaller, and does not need as many amps to recover the same percent amount of charge. So, to go from 50% SOC to 95% SOC takes roughly 5 hours in both cars.
While the salesperson might have misled you, you will very likely have no problems charging your car overnight at home. But if you are an Uber driver, or some such, and want a fast charge whilst you are having lunch, you might want faster charging. Otherwise only hit a Supercharger when you are on a road trip.
I really like our M3 RWD. I think it is the best Tesla made.

I mean, technically, one could drop the battery and replace the PCS. Going rate for those seem to be about $500 on eBay, used. You'd need to make sure it's the 48A version. Or you could try ordering directly from Tesla.
M3 RWD charging at 40amp after PCS replacement?
Hello, I’m a new owner looking for some help with a very specific question. Hoping someone here has the answer. I recently bought a 2020 M3 SR+ RWD. I had a Wall Connector installed on a 50a breaker so it’s configured to charge at 40a but the RWD M3s only charge at 32a. Still following? Please...

I didn't post this to be snooty and contradictory (okay, I did), but seriously - if the OP was asking "How can I get my RWD 3 to charge at 48A no matter the labor and cost?", this is the answer.
If the OP is willing to pull their car apart and replace the PCS, this is possible, otherwise everyone else is correct - the hardware in your car is physically limited to 32A.
And really... the extra 16A is almost negligible - just charge overnight.
And for anyone considering doing this, there's always the possibility that this could damage something and/or void your warranty and/or require software help from Tesla (which would mean they would have documented that you'd dropped your own battery and swapped the PCS).
In no world would this ever make sense to me.

Not just to get faster charging, but for an out of warranty car that needed a PCS replacement, anyway, it could make sense.

I’m sure it would void any sort of warranty, and might require some Toolbox programming to make it work, but sure, I’ve no doubt it’s possible.
This is a good point. If you have a failed PCS in your RWD 3 and have to repair it out of warranty, I'd totally push for a 48A.
This is a brand new M3 SR, I would not make any changes, especially changes that void warranty. Having a Wall Connector is not bad, it looks better and is safer than using a 14-50 outlet and Mobile Connector. The 14-50 outlet has to be very high quality and the installation cost is the same as for Wall Connector. Actually, the 14-50 outlet solution may costs more as the circuit breaker have to be GFCI type.
My main complaint is about the sale woman says some thing that is not true for my M3.
My fault is I did not do any research about charging. Now, I know this quite well (learn more when having issues).
My next EV will certainly can charges at 40 amps, damn sure about that.

There was one person on here who, when Tesla did a PCS swap on their SR, ended up with 48a charging. Seemed to be a mistake, but it worked fine.
Not sure what you're referring to about the salesperson misleading you, but 32A charging is plenty fast. It should be fast enough to replenish the entire battery overnight, something that almost no one needs to do.
Well... at 32A, you'd be charging at 7.68kW (32 X 240v = 7680).
The battery on your car is 57.5kWh capacity, so at 7.68kW, would take about 7.5 hours... except you're not going to charge from 0-100%. At *most*, you'd probably charge from 10-90% (although even that is an extreme).
So I'd say this salesperson was actually spot on. That said, this isn't something I can ever imagine myself being upset about, not in any universe. "The salesperson said my electric drill would take 2 hours to charge but it actually took 2 hours and 23 minutes... shucks".
