Fuel pressure is a bit high for a stage 1 which normally uses the standard pressure.
Standard fuel pressure is 50 psi (3,5 bar) with regulator disconnected.

Check with castle what fuel pressure you should use.
Or try a standard chip at this pressure and then the standard pressure.

N.B.: Even with this fuel pressure you should not get misfires due to over fueling.
If it's only with the castle chip then I would recommend to find another supplier.
