Model 3 Performance feels slow?

Do we know if there is any performance left on the table at this point? Especially in the 80-130mph range. I imagine we would need gearing to help boost performance at the higher speeds. I think the car pulls pretty good up top it is just noticeably less than the ridiculous pull we get at lower speeds.
I still believe the car has more to give off the line. I am sure traction is an issue so max power is not delivered off the line. This is where launch control comes in and you can use it if you have sticky tires on the car or you are at a track that is properly prepared.

No. Ludicrous mode was available for the extra cash because those cars got extra thick cabling. The M3P is already at it's peak performance with it's standard wiring.

I’m not sure we can 100% say this either way. Unless you know something we don’t.
Yes, there is no way to know unless you are an engineer for Tesla. I believe there is more power to give but feel the issue might be tracktion and of course Tesla has to be concerned about burning their motors out too quickly especially with 8 year, 120K warranties on them.

Maybe. Only thing indicating that the 980 isn’t tapped out is that the SR+ uses it and gives more power from it than it does in the performance. I’d lean toward it not being at its max because of that... but it’s not too different than the SR+ output. So hard to say, but likely a bit more juice to be offered.
Has been speculated they held back some so it the P didn’t outperform the prior ludacris S

Where does it say an SR+ rear motor is more than a Performance? Instructions I have says they’re the same.

Agreed; I don’t think a Performance is maxed. Overly simplified, but taking nominal voltage (not peak voltage) and max amps from the instruction manual suggests 600HP (448kW) is possible.

Here you go : How Much Horsepower Does a Tesla Model 3 Performance Actually Have? | MotorBiscuit

Seems Misha Charoudin has done the dyno, I think he can be trusted.

Unfortunately that guy knows little about dynos or cars and cannot be trusted.

His data purports to compare the (red) 2021 to an older (blue) car but he has clearly configured the dyno to display "corrected" torque values using very different powertrain loss curve estimates and/or gear ratio inputs for each car so it's likely that both sets of data are garbage.

Whichever car has more torque at a given speed must *always* have more power at that speed since both cars use the same 9:1 gear ratio. It's mathematically impossible for the power curves to trade places (as they do here at 80 km/h) without the torque curves also doing so at the same speed.
Power = Torque x Speed.

Power = Torque x Speed.

After watching the video I agree the data can't be that far off. Most tests show around 500hp now after the power updates and similar torque figures but I think these dynos designed for ICE based vehicles can't be trusted 100% just yet.

Yes, it's unfortunate that we're fixated on "crankshaft power" guesstimates loosely derived from dyno data rather than just seeking the important, meaningful, useful and *accurate* raw data right from the dyno which tells us everything we want to know - torque & power at the wheels. This misguided convention makes EV-ICE comparisons even more difficult than they already are due to the vastly more efficient transmissions typically used in EVs.
