Default Why does it not hit strong

Well im on a 100 shot now went back down, on the 100 shot it just doesnt hit hard at all its more like a 25-30 shot. The bottle pressure is about 900psi i have a bottle heater the solenoid works properly i pulled the hose off after the solenoids and sprayed it. The hole on the nozzle is facing the right direction. The only thing i can come up with is could it be running lean. The car runs perfect on motor and i have a tune for nitrous as well for a 100 shot. I dont know if i should back down even more to a 75 shot and see how it pulls then. I think if it pulls harder then it would have to be fuel.

im using .048 according to them thats a 100 shot. Im going to have my #8 plug removed on wed to see what it looks like. I think within the next 2 weeks i really need to put it on the dyno and get a/f as well. Now a days there charging 150 to dyno a car with a/f readings.

actually i went out there and took it down more to 75 shot so a .042 jet. If it hits hard on this jet then i should be running lean on the higher jets.

Ok on the way home tonight the 75 shot was wayyyyyy better then the 100 shot. All i did was disconnect the hose right at the jet and sprayed it to see if it worked maybe it also cleaned the line out i dont know. The 75 shot is way better ill go back to the 100 shot and see how it is maybe it was a dirty line or the a/f is better with the 75 shot even thought i have a tune for a 100 shot.

Thanks guys i just ordered it through summit appreciate all the help. Im going to probably get this and the nitrous pressure gauge and put both on a pod so i can keep an eye out on things better from the drivers seat. Not to be a PITA what nitrous pressure gauge can i buy to use on a pod i have one on the bottle but would be nice to hook one up were i can see it from the drivers seat.

Thanks hodge9386, appreciate the help. Once i get the 02 readings i can send it and let my tuner know so he can dial it in.

i just realized this is a DRY shot?
see, if it was a wet shot, you would be able to mess with the fuel yourself with out having to see your tuner...

I have ford svo 30lb injectors that i have not yet installed. After i find out the a/f and see if its running to lean ill go ahead and install them. Most i want to run is a 125 shot dry but i think im gonna have to install the injectors still even at that.

Instead of running it lean, taking a chance on toasting it, maybe install the new injs, and then tune from fat to lean, instead of the other way??
