At the risk of asking what may seem like a stupid question - are you sure the DSC isn't kicking in? If it does, the yellow light (that comes on when you switch DSC off) will come on momentarily. This will absolutely cut the throttle way back. You get around this by switching the DSC off.
Other questions - do you have sport mode on? This quickens throttle response.
The engine is very tight when new, but it shouldn't have any lag as long as you're keeping the revs above, say, 1200 RPM before the clutch is fully engaged. The engine develops a boatload of torque from low RPMs - do NOT slip the clutch at higher RPM - by about 2000 it MUST be fully engaged or you'll burn up the clutch in a hurry.
