What is the voltage and current rating of the transformer?  Are you now using
a rotary gap?  When I first tried to fire my coil with the new pole pig
(after running with 12kv, 120ma neons) I could not even get the same
performance that I had with the neons.  My static gaps were not quenching all
the current supplied by the pole pig and would essentially keep the output
voltage of the pig clamped at a low value.  I built a rotary (now operated in
series with a static gap) and have good performance.  Good quenching of the
