Default Nitrous surge at activation

Here is what happens,when I go to spray for the first time after I open my bottle it surges!I will go WOT and then hit the nitrous button and then it will jerk like there is air in the line,but there isn't!I have a purge on it and have purged the **** of of the bastard over and over and everytime I hit it for the forst time after it has been sitting for days it jerks and then hauls ***!I do not like that seeing that really puts even more strees on the tranny than the nitrous already does!Does ANYONE have this problem?
I have a bottle heater and I keep the pressure at about 925-1000PSI all the time before I spray it and have purged it like you would not beleive to see if that would help and it really does not help!This problem is really starting to **** me off!
Any help here would be great and appreciated
Thanks guys

sounds like you have an air leak in a line somewhere......like when you have a vaccum leak...the engine will surge......sounds like you have a leak somewhere......check all your lines and check your timing.......what is your total timing set at?

try leaving it in park and rev it up to about 3000-3500 and hit the nitrous a couple times then go out and run it and see how it does then.

DO NOT DO THIS

"try leaving it in park and rev it up to about 3000-3500 and hit the nitrous a couple times then go out and run it and see how it does then."


Could the jerking be traction issues when it first hits? what kind of jerking, what kind of rpm changes do you see.. has this happened every single time? It's not going to be any kind of air issues

I AM NOT putting it in park and sprayin like that,that is crazy IMO!
What it does is when I first hit the button it falls on its face and then lurches HARD,this hesitation and then jumping up and haulin *** like that is causing worse traction issues that I already have!It jerks but what it really does is fall on its face right when the button is hit and then hauls ***???
I am thinking about putting a shorter braided hose from the noid the the nozzle to see if that helps any!

also check to make sure you don't have a bigger fuel jet than you need. slowprocess was having this same problem and he found that he had a bigger fuel jet than needed.
