Youre on a tangent now...
The quote compares a turbocharged application to a NA application.
The OP described an issue. The relevant parts of the system that alter the spooling characteristics have not been touched. The natural lag associted with the system is still present. The turbo is not lagging anymore than it did prior to his fmic install. To say the cause is turbo lag is incorrect. The culprit is throttle response, and the need for a tune to account for the pressure drop in the system.
