I still believe there will always be the transient response issue (however slight) with turbos, but they should never upset a car mid-corner.

Oh, I can't disagree with that but in the same regards, their is a throttle response delay with NA as well. Every system will have it. You can't change the laws of physics and gas dynamics.
For the others, yes, turbo lag is always terrible.
It is ALL about sizing.
Now what I can't emphasize enough and most seem to lack the grasp of is that lag is not the same as a delayed response in throttle (or transient response or 'throttle response'). If your turbo lag is over at 3k and you are into your torque curve, coming back into the throttle from a corner at say 4000 RPM, there may be some slight delay in power onset, this is your transient response. If you are coming off the corner at 2500 (you suck at driving), you are dealing with lag, as the turbo can't be spooled yet. It's the same as 'falling off the cam' on built NA engine. Out of the powerband is out of the powerband and that is on the driver.
