Which system is the best? What tune do I need. I have a diablo sport tuner. Pretty much looking for any input i can gain. thanks

I think a lot of people go with the ZEX kit. Depending on how large of a shot you're going to be spraying will determine how much you need to buy for it. I'd recommend if you go with anymore than a 125 shot you look into getting a purge, bottle opener, bottle warmer, and gauges. I'd also look at the Speed of Sound switch panel that goes inside of the cup holders.

If your going to go over a 125 shot you'll also need to upgrade the fuel pump so you don't lean out.

I use the Zex kit and Im happy with it.

Oops, left that out. I also forgot to add that you'll need a tune and colder spark plugs with a bigger shot.

Yep! We both forgot that one![&:]

There's a bunch of threads on whether or not you need a tune with a 75 shot. Check them out and decide for yourself.

Personnaly I wouldn't run any shot with a custom tune thats not made for Nitrousas most non-nitrous custom tunes adjust timing in a manner that can cause problems with Nitrous. The Zex paperwork explains everything in depth.

Can you use nitrous and a cai and tune together? Then switch tunes for when your not running nitrous?

i used the zex kit. pretty safe system but i only sprayed 100 shot. you should get a tune but ive read its not necessary for under 100.
