I would not go to a higher converter, what is the car flashing to when you launch on the spray?
with my 4K converter and a 150 shot. at launch it would flash to 5700rpms. and shift at 6500, there was almost no first gear. if the converter you have now is a NA converter and real loose. I'd swap in a 3200 nitrous/blower converter which will be alot tighter. It wont flash a ton on the hit, or at least as bad as a NA converter.
