No. A tunable is just a mechanism for setting a variable very early in the boot process. A sysctl is a mechanism for getting/setting a variable while the system is running.

There is probably a class of variables that may need to be tuned before the system is up to the point where rc.sysctl runs, yes. = Mike -- Where am I, and what am I doing in this handbasket?
