That is interesting, Dada.
I discussed the tuning option with my dealer and he put me in contact with a client who had the remap done and a Williams Sport Exhaust fitted.
This client, very generously, let me drive his tuned Plus 4 to feel the difference to my standard one. Which is what I just did.
It felt not as a huge increase in power/torque. Just a bit more breath. Power delivery felt 'easier' (don't know how to describe it more accurate).
The exhaust was not really LOUD, but a bit to intrusive for my taste.
The guy from the maintenance department at the dealer said the sport exhaust was really needed for the tuning to be effective.
But your experience is different. Interesting...
Even more options to consider.
