Nitrous Outlet LT1 package??
From what Chris told me that brand works really well..only problem is you will still need to piece together some other stuff to go with it. This is the main reason I am getting the first package I linked up top at the begining of the page. Comes with all the saftey stuff and IMO the plate set ups are the way to go 
, maybe just a window switch & heater, i've seen many run VERY good with the single valve set-up, one guy was knocking off a solid second & 10 mph on his with a 100 shot, he didn't even have a heater/window switch, hell not even headers, just had the PCM tinkered with, he was laying down 12.4s/12.5s @ 111-112 with an M6 
You will need the NGK plugs on top of that package you were looking at...which is dirt nothing..I'm actually going to piece together that same package you like. I'm gonna add the plugs, fuel press safety switch, window switch, plate conversion, the bracket to mount the bottle in the back and the switch panel for the ash tray. Still debating on getting the purge kit and bottle opener.
That def doesn't sound like a 250 shot. I hit 117mph with just a 100 shot and a couple bolt-ons on my vert..
