I have a Trailblazer SS RWD with an intake, 160 tstat, and msd wires. Im installing a ZEX Nitrous 100 wet shot tomorrow. I have a WOT and window switch.

What plugs do I need?
How do I tap into fuel?
Am I safe without a tune?
Do I spray before or after the MAF?

THANKS!

1. You need one heat range colder plugs
2. Tap into the fuel test port or schrader valve
3. You can be safe without a tune but take it to a dyno and see where your a/f is at.
4. After the MAF

i love forums. thanks and thanks. Any other suggestions?

Do i need to know my A/F during nitrous use or N/A use? Im sure i can find that out with a tech 2 (GM Scan tool)

The Tech2 won't show you wideband A/F...only narrowband and that won't help.


Definitely invest in a wideband setup, or have it checked on a dyno. MarylandSpeed sells an LC-1 w/ digital gauge setup for $259 shipped.

This is a LS2?
Hard to beat TR6 plugged gapped at .035"
On the front of the driver side fuel rail is a cap, take that off and you'll see the schrader valve (basically looks like a tire stem valve). Remove the schrader valve and tap into the rail.
You really should get a tune. If not, start out small and check it with a wideband. Then work your way up.
Dry shot goes in before the MAF. A wet shot goes in after the MAF. I highly recommend a TB plate, like what Nitrous Outlet sells.
