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.

 

bump...posted in the middle of the night and got lost in the shuffle....any advice? or comments

 

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.
