Thanks all that have viewed and contributed.

I do believe that the car will handle considerably more power. Cars in general are detuned for world wide international markets providing garbage fuels, and to hit emissions targets among other things. Also - if the T4 was more powerful than a T5, who'd buy one unless you needed 4wd? I sold BMWs for a while and had these discussions many times - the M2 was a great example. The M240i was a far better car IMHO, almost as fast with a detuned engine so they could sell the M2.

However, as posted in another thread, after considering other map providers and the potential pitfalls, and doing some thinking about how I'll use the car over the next 23 months - A roads and dual carriageways - with 11 months of MD warranty initially, I'm gonna stick with Polestar, so it's booked in for 17th at my local dealer.

Cheers.
