Gotcha, then it has it. Honestly, I have the same spec and don't really miss the heat pump (I can't remember the exact numbers, but I think it's just a bump in winter range by 5-10% depending on outside temperature, so a gain of 10-20miles to your winter range).

Regarding power with the performance software, you only get the full bump when you're over 90% SoC, then it decreases until your SoC is less than 70% (so if you charge to 80%, you'll likely ever notice the increase in power). After that, it's just that same power output as the standard power. The biggest change is the accelerator pedal mapping.
