Tobias,

For the final tuning adjustment, this should be done by trial and
error using full power tests to obtain the longest spark output.
The sparks themselves produce capacitive loading of the
circuit which lowers the resonant frequency of the secondary.

Some folks install a remotely controlled tuning coil in series
with the tank circuit, so the tuning can be adjusted in real-time
while the coil is operating.  This usually will not give you longer
sparks over the trial and error method however.
