Plus I went through two of the "control" boxes because they wigged out and if I armed the master switch it was spraying. Ended up ditching it and going with a NOS system.

Now to Zex's credit they sent me a new box each time, and I'm sure they fixed the problem (again, they were brand-brand new when this happened) or they wouldn't still be in business. Really "user" friendly system and easy to set-up, although the box takes up a bit more room than other systems. I did however LOVE their purge valve. Worked better than any other brand.

But back on topic: 50 shot you could get away with running a colder plug and that's about it. For a 75 I would run 2 steps colder plugs and dial back your timing.
No Echonova it's not that I don't want to hear what you have say, This is the info. that I'm looking for!! I'm trying make up my mind on if I should even put it on, It's just that it's been in a box for about 3 or 4 yrs and I was thinking that it would be a great time to use it!!
I'm guessing that you did dyno your REX to come up with those numbers??
Did you ever run that setup at the track??
