I have a 100 shot dry on my car. i have a hole poked through my air cleaner with the nozzle run up thorugh it sticking out. first i tried pointing the nozzle towards the mass air flow sensor, and when i squirt it, it would would pull real hard then start surging. So i thought maybe i was freezing the needles on the mass air flow. So i turned it aorund facing the opposite direction. Squirt it does not even feel the same. So maybe i thought the bottle was emptied the first direction i had the nozzle facing and the bottle being emptied was making it surged. went and filled the bottle. had the nozzle facing towards the mass air flow sensor. nope did the same thing. i need some advice on how to do this. thanx tom

 

What system do you have??

On a NOS, check your FPSS and adjust.

 

i threw it together. it is a nos purge solenoid. with a nozzle. i am shotting 100 shot to it.

 

Give me more info on your motor, year of car.
You could be running out of fuel (Not Good)
Try shooting a 50 shot and go from there.
