Can I spray the 125 shot?
i have a 99. i spray my 100 dry shot at 1000psi and i'm at 99% injector duty cycle.
i use hptuners and so i have taken out a few degrees of timing past .76 g/cyl. no lean spike, and my narrowband o2 sensors are registering 900+mv (actually 902mv bank 1 and 941mv bank 2). i realize my injectors are smaller, but i would seriously consider upgrading injectors.
hptuners thinks i'm putting out 480+ lb of torque. i assume it's inaccurate because the pcm thinks i'm taking in more air than i really am. anyone else with hptuners use the torque pid?

How big are the 99 injectors?
Have you ever run your car? If so, how did she do?
How accurate are the millivolt readings on a narrowband? Are they usefull enough to tune with?

we have an 1/8 mile track here, but i've been hesitant to run there - not interested in upgrading rear end to handle DR hook and not enough traction to hold the nitrous shot early enough to make a difference on the short track. i'll likely end up there in the next few weeks, but i'd prefer to drag some people with me out to the closest 1/4 mile track.
here's a shot of my hptuners data. you can see the INJector readings jump and the timing drop when the nitrous hits. i think i'll switch to a dual nozzle setup for reasons others mentioned. i notice my iAT barely moves.

With stock 02's my millivolt readings are pretty steady at 940ish while spraying(after i moved my nozzle of course), i was told that that is about 12.2 afr, im planning on just leaving it be. Haven't had a chance to take it to the track yet, its just been too damn hot...milk was a bad choice
