Of course with an automatic tranny this lag is masked by the furious downshifting that will happen. And with a little upgrade in driving skill this lag can be accommodated with a stick shift. And with a little experience you don't notice it so much.
That is silly. 2000 RPM in 6th gear isn't going to yield acceleration regardless of whether turbo or NA. Torque may stabilize quickly with a NA car in that scenario, but we're still talking hardly any torque at all and certainly less than what the turbocharged car is putting out in equivalent RPMs. You're still going to net better acceleration in the turbocharged car until you get to ~5k RPM when the NA car sees its power and torque come to life. But of course, if it's your first turbocharged car, it's definitely a different feeling that what you've been used to.
