n.o.s. trouble
ok i am running a direct port 120 shot on my lsvtec. when i turn it on at about 4500-5000 it bogs the first time but then it doesn't bog at all while i'm in it and goin from gear to gear. i have a fuel pressure gauge on my hood and it goes down. i have a 255 bbk fuel pump in it and pressure set at about 45psi. it is a wet system.

Do you have a purge kit? Do you purge at all? It could be going momentarily rich when you first hit it because of air in the nitrous line. Try putting the car in neutral, rev it up to about 5k rpm, and hit the nitrous. The motor will rev up on its own. Do this a few times and then take it on the street and see what it feels like. If there is no more bog, you just need to purge before you hit it.
yeah i have a purge kit. now if it is momentarily goin rich then why is the fuel pressure dropping. yeah in the nos book for the kit it talks about 45 to 48 psi. i've tried puttin it around 35 but it leans out way too bad.
