NITROUS PERFORMANCE PROBLEM

I installed a Zex 100hp wet system. Install went great.. No problems. Window switch and WOT tested and work perfectly. Heres the problem.. We tested it this afternoon and it really didn't seem like that big of a kick.. In fact, I had to pull over and check the system to make sure it was firing.. It was. The car has lots of bolt ons, and has a real kick in the seat to begin with. JLT Cold Air, JBA Long Tube Headers, Borla Exh, IMRC Delete, Bama Custom Tune, and 4:10 Gears. The gearing always made the car accellerate like a bullet. With the NOS Armed, we thought we felt a difference at 5000+ rpm, but it is so subtle, I feel like something is not right. The window switch is set to 3000 - 6500 rpm, plus WOT. I even tried bypassing the window switch (I included a switch under the hood to allow the mode swap), but again, the same result. My basic question is with my current setup (especially the gearing), under what conditions would I notice the biggest difference? We performed the exact same runs with and without the NOS armed and although we had to keep things under 110mph, (due to where we tested), there wasnt much of a difference. Shouldn't there be a HUGE NOTICABLE Difference? What am I missing?

no even from a roll i did not notice a very big difference............ what conditions would I notice the change the most....and again isnt it supposed to be an obvious huge difference...... does it have anything to do with my 4.10s............ is it possible its already accelerating so hard that the change is only noticible when timed? im kinda lost guys help me out here

I have a .46 nitrous jet and .30 fuel jet in.....those were the jets for a 100 shot in the back of the zex manual.... the bottle pressure was 800-900 psi...... i do not have a purge however i ran enough passes so that any air in the line would be gone..... any ideas?

its for 900 psi on the bottle and I believe 40 psi on fuel i dont have a bottle warmer but im in nj and it was a warm day and bottle pressure was consistant............. when you say a 100 shot in zex is like a 75 shot are you saying i just need to up the shot or something else is incorrect..... to my understanding a 100 shot is the most stock internals can take on my car

well i tried it today when the roads where dry (werent yesterday) and really felt the difference....it was great! thanks for the help guys
