I am looking into purchasing the ZEX kit for a grand and know I need to tune specifically for any shot above 75. I don't really have a speed shop around here that can do a custom tune so what are my options?

Can you use a predator to customize your ignition timing/fuel needs safely or do you have to buy a canned nitrous tune?

Also, I would like to use the 100 or 125 shot for maximum gains but would like your opinions on safety!

New member here and appreciate all of your help.

To run 100 shot safely all you need to do is pull 2 degrees of timing and run one step colder plug. For a 75 shot I would not pull any timing, just run the colder plugs.
I ran my 5.7 that way for 2 years before I sold it. I never had any issues.

Did you make any Dragstrip passes on the hose? How fast?? Did you only run the 75?
