Going to be installing some nitrous on my 06 chevy 5.3 comp cam xr269hr, cai, exhaust with lts. Trans is slightly built. Larger pump, higher shift pressures, etc. what kind of wet shot can I put in with stock plugs and tune and what can I use with changing some stuff? Here's the kit: http://m.summitracing.com/parts/zex-82047

 

You don't want zex products. A nitrous express proton lot would be sufficient for you.

 

The Proton Plus Drive by Dwire system would be a direct bolt on for you and will flow 150hp straight out of the box, and can flow up to 250hp with a few extra parts.

Thanks for all the advice.

 

you have a cam in that 5.3 and you're wanting to spray it, all on the stock tune? I'd suggest you invest in a tune, a real tune, not a hand held, before you go to spraying it...

 

I have a zippy tune

 

There is a lot wrong here. For one you don't want to run stock plugs with nitrous. You want to go a step colder and use copper tip plugs. No platinum or iridium. Also as mentioned you will want to get a real tune for nitrous. COntact Zippy and tell him you will be using nitrous so he can adjust it. Common rule is per 50 shot to pull timing.
