2002 lq4 stock bottom end... 243 heads, fast 92, nitrous outlet plate, 228/232 .600/.600 112+2 cam. Maximizer 4 prog controller NA tuned with LNC-2000 for timing. 200 shot with 7 degrees pulled on ngk 8's for plugs. Racetronix 255 pump pulled fuel from rail..pressure drops to about 55psi from 62psi at wot on spray. 93 octane in tank on stock lines and 42@43psi bosch injectors. Starts at 60% of 200 out of hole and all in after 1.2 seconds...
Changing to dedicated system for nitrous this season, 250-300 shot on 8 degress pulled with 9's for plugs and 112+ octane in dedicated system...that's the plan anyways...see where tuning takes me or the tow truck. one or the other lol

DISCLAIMER: You will break $hit running big shots (that's part of going fast), sooner than later if you are not very familiar with running nitrous. I recommend going no higher than a 150 shot if you are new to this. With that being said....
I've tried it every way, progressive, 2 stage, and single stage with mine. I was running an odd 2 stage set up when I tried it that way. 100 shot with a single nozzle before the throttle body that turned off at 4500 rpm then the 300 direct port would turn on at 4700. I'll spare you the details but I had a hard time getting the bugs ironed out with the unorthodox 2 stage set up. Running it progressive works the best but my Maximizer 4 has recently developed a mind of it's own so I'm running it as a single stage right now, gangster style with a bang button. I hit it at around 4200 rpms and get off when my shift light comes on.
I DO NOT recommend running it this way (big shot, no window switch, single stage, no progression) as this is a recipe for disaster if you don't have experience running spray this way.
Anyhow, B9EFS plugs gapped at .026 with C23 in a stand alone, 12 degrees total timing.

my 4an main line, and stalled auto only got 170whp with that shot tho. Just upgraded to 6an main feedline. If my wideband goes lean on the spray, then the 4an was a restriction.
