Turbos are not instantaneous power, they always take a few seconds to spool up, usually considered inefective below around 1200 RPM. but the shuddering is not usually caused by the turbo. As an A&P, if I got that write up, I woould first check the mixture, and if that checks good go to the timing..... then go from there...... partially blocked fuel injector, etc. Do you notice a slow climbout, or what is your max RPM on the Run-up, what is the mag drops?
