LS4 N2O Quick Questions. I am really just wanting to get some assurance I am on the right track.
I am going to add a 100 shot wet NX kit to my 08 Grand Prix GXP.
Current mods: CAI, High Flow Exhaust, HP Tuners tune...No timing change.
I am pretty sure I will be ok with a 100 shot on factory timing, since I havent added any I should be good...correct?
This is my first install of a N2O system, I believe I can just take out the core from the test valve and tap in there....but do I need an adapter? probly.....
.028 is good for a gap on the plugs? and 1-2 degrees colder? I have done ALOT of reading and studying but I am hopeing someone who knows what they are doing for sure iwll chime in and gimme some advice or confirm what I am saying.
Let me know what you think....Thanks in advance.

You should be fine on 100hp shot with the stock timing but since you have HPtuners i'd pull out at least 3* to be on the safe side of things. For the plug i'd suggest getting a NGK BR7EF ( Stock# 3346 ) and gap them around 33. Other than that you should be ok spraying the 100hp shot on the vehicle.

I already got the plugs they are Pulstar AD1I, (no opinions on the plugs please), I conacted them and they are 2 steps colder than stock plugs...and 33 on the gap? I thought it was smaller but you are the pro...I do not hav the HP Tuner...I will have to get it done but for safety sake I will get it done.
