I have a gdi and mine also has a non-linear power (torque?) delivery.
That made me think of a remap but this is only available with sports exhaust, which is a bit too much ‘Golf GTI-like’ to my taste.
I’ve driven 8000km by now and it seems to loosen up a bit. Could also be that I’m more used to pushing past this flat spot asap when driving.
A remap without the noise would still be very welcome, though.
