To those with March builds that don't find it droney, perhaps it wasn't the 1st of March when the changes began. Maybe you don't have the changed exhaust. I never drove the pre-march build turbo so I'm not comparing to anything but I still find it droney. You can adjust throttle to compensate a little but unfortunately that has me driving around in third (auto) most of the time instead of overdrive which means I'm burning more fuel. If I have an option to change to the pre-March muffler then I think I will, although I still don't know how it sounds, I assume it's quieter.
