hooking up a zex system but the instructions said that if you have had the computer tuned that the timing might need to be adjusted.
I have the JMS cold air kit and the tuner package that came with it. I am only using a 75hp shot. Do I need the timing adjusted. has anyone else had experience with this yet??

A performance tune will have 33-35 degrees of total timing. My car was tuned for nitrous with 22 degrees of total timing on a 100 shot.

Take it to a professional tuner. A good tune is a lot cheaper than a new short block.
