I have a 98 a4, Im running 125 wet shot,tr6 plugs,walbro pump,and has been tuned for 125 shot.
the car seems to run fine on motor but when I try to spray it you can barely feel it kick..it doesnt detnate,ping pop hiccup and its not throwing any codes.
I checked both solenoids and they are both working fine,The car was taking the juice fine it just seemed to start falling off and running slower and slower ##'s on the spray..It went from running 7.30's to 7.60's and the last time I tried to shoot it it ran a 8.0 on the bottle and backed it up with a 8.23 on motor.
Im running 55/32 jets
Any ideas?

 

Bottle Pressure? Do you have a heater?

 

yea the heater deff. helps or just a good ole torch

 

tourch is not a good idea at all. stick with the heater. but ne way maybe u should check with ur tuner. id do that and see what he says

 

Somethings wrong. your either down to a pound of nitrous in your tank or its 40 degrees where you live and your pressures down to like 600 pounds.
Thats really all it could be.
Well, possibly some foriegn object got into your line and is causing blockage.

 

Just because the solenoids are clicking, or opening doesn't mean that they are good. Sounds like you have a bad nitrous solenoid. Borrow someone's solenoid and put it on. See if it doesn't fix your problem! Fuel vapors are bad for the solenoids, and over time they'll crap them out! I've run into this time, and time again!

 

Dont ever tell anyone to use a torch again. Its stupid and proven dangerous.

 

My solenoids are pretty old but I took the lines off the nozzle and activated the wot switch and sprayed a good bit into a bottle to make sure they both were working.I'll still try to swap them out and see if maybe it just isnt opening all the way or something...
this kit has been on 7 different vehicles over the past 4 years Ive owned it..lol
I have a heater and I keep a close watch on the gauge and make sure my pressure stays up real good,so that cant be it
If it was for some reason leaning out,wouldnt I get some detnation?
If I cant figure it out this weekend I talked to my tuner and he told me to bring it to him and stick it on the dyno and see if he can figure out whats going on

 

Just swap the nitrous solenoid, don't worry about the fuel. I know it sounds crazy, and I'm sure its spraying nitrous like crazy, but its probably not spraying enough. I've seen this many times!
