For anyone running an '11+, you should not run anything more than a 75 shot with a stage colder plug because you can not pull any timing at all. For the earlier years you can safely run a 100-125 shot on the 5.7L with a stage colder and pulling 2-4 degrees of timing. Some of the LX guys are running 2 stage colder plugs, pulling 4 degrees, and pushing 150-175 shots regularly, the engine will take it no problem.

From what I've been reading, the Zex kit measures their jets at the crank and places like Nitrous Outlet measures at the wheels. If you want the best, the N.O. plate kit is an absolute thing of beauty and I'm kicking myself for not getting that instead of my ZEX kit.
