What's your bottle pressure? Plate or nozzle?

you were at kdale a few weeks back right? red truck? what size jets are you running? no trash in the lines, bottle pressure at 950psi?

Wrongs jets, maybe backwards. low or close to empty bottle.

I would look over the entire system. You have the wrong jets, clogged line, low pressure, kinked line, clogged nozzle. Something is very wrong so it shouldn't be hard to find. 175 should feel like a world of difference so it isn't like you are just a hair off. Goodluck.

Hes right, with a 175 shot you should be doin this--
Good luck to finding the issue

i believe i have 67 nitrous and 38 fuel.. nos bigshot seleniods.. not pinched lines,no clogged line or fogger..if i take the fogger out and spray while im holding it, it almost blows it outta my hand..ive heated the bottle to like 1200psi and its still real lazy on the spray..i figured with all ive got done my truck should run mid 7's with ease on the spray..also could any of you guys tell me what pills i should be runing for 175.? also i think my tune may be messed up i havent yet dyno tuned it with a wide band yet.

I've never used nitrous on a fuel injected app with a nozzle. But I've always used N.O.S. kits with carb setups and the fuel jet was always bigger. I know back if the fuel solenoid stopped up or had trash in the line with the 250 h.p. jets in, it would barely hit and seem real lazy on my carb setup. May not be right but my guess is check the jets.

the fuel jets were of course bigger back then on carbed setups as they only run like 5-9 psi fuel systems. not 45-60psi setups like efi...
