I have a 408 l92 intake nitrious outlet spray nozzle in front of throttle body.have a stand alone 112 for nos.okay sprayed today for first time 150 felt like a 25 shot barely pick up .10 psi fuel pressure 6 degrees of timing pulled with lcn-2000.and some old nitrious works solenoid.do y'all think the noids is the problem they both click when activated but I think a 150 should hit way harder well it sure did on my old school 406 with plate

 

Do you have a purge? You may have alot of air in the lines-

 

I would check solenoids and also check for leaks between solenoid and nozzle. Do you have a window switch? Are you sure it was in working order?

 

No I don't have a purge I just bleed it the old school way,crack the line till nos come out

 

do you have a bottle warmer and pressure gauge?

 

Bottle pressure was 950

 

Do you know the orifice size of the solenoids?
