Sparyed the 408 with TNT F-1 I installed the kit awhile ago, got a great deal on the whole thing w/ purge for $400 used. So went to a local shop to get the 15 lb bottle filled (old dry nos kit) got it back with a good 1200 psi 
I put the 100 shot jets in for the test drive. I must say that when i sprayed from a 40 mph roll and i was surprised how hard the 100 shot felt with this kit. i know it was a little more than 100 shot right from the start, plus the 1200 psi helped that out a bit. I noticed the car did surge a little as i shifted at 6900 rpm.....think its time for a new fuel pump...still using the stock pump with 42lbs injectors..So no more spray until the pump goes in!
I did get the purging down pat though.lol...the pruge came with blue led lights..i thought it was very "ricer" until i hooked it up, pretty cool looking IMO
next is to come is track times

Damn, that is going to make some SERIOUS torque 
. At 1200 psi though, that nitrous was coming out FAST, so it was probably more than a 100 shot (someone correct me if I'm wrong).

Yea, increasing the pressure over manufactures psi rating is like up-sizing the n2o jet. Good as long as you upsize the fuel jet also or you could be lean. Maybe your fuel system is ok, and just running a little lean, or maybe it's on border anyway?

You need to get you a good fuel system. Thats alot of power you have, and spraying it needs more. Take my word for it. Fuel is like insurance, better more than not enough!! I have T-rex, 255 in-tank and 42lb injects. Just to be safe!

Just so you know, that is probably a pretty lean shot even with the right fuel system. I recently spoke to TNT and they said they're kits are set up for 900 psi. That's why so many people think they're under rated, they're spraying them at 1000-1100 psi and leaning them out a little.

They work GREAT you should've seen my flow numbers on a 3.903 bore. Thanks again for that and good luck on your project!

Yep will do, I go there some Wed days but havent been in a while! It might be awhile b4 we get to see the full affect...right now I'm still with the stock 5.3 and all the little bolt ons. But those heads I mentioned, and a 383 stroker are at CNC in Manassas right now getting built. You should see the internals I have in this monster everything forged, mostly power coated (from rods,to pistons) I'll have some pics of it probably by the end on next week hopefully. But that engine, the N2O, and the 4L80 are going in at the same time
