It matters little what gearbox the car has. If you want an improvement, you have to keep the engine spinning faster all the time to negate turbo lag or go to a 6 cylinder engine.

As C&D showed and the poster above noted, it's not purely a question of turbo lag completely but instead the transmission programming having it in too high of a gear at very slow speed (when it's not in sport transmission mode) and then requiring time to respond with an appropriate gear change all the way to 1st gear. Once that time period has elapsed, then you are dealing with turbo lag since only then can the engine start to generate enough rpm+fuel burn to spin the turbine up in speed.
