sorry........ my set up is a HSW single nozzle dry set up.....I have a FPSS set at the standard 35psi......bottle heater......the pressure was roughly 900 when used the nitrous.....and a purge. I also have a dual stage rpm window switch.
It was really surgin alot which tells me its rich ? I moved the nozzle a bit (10-15 degrees up) and it surged less but it still surged. My nozzle is about 5 inches from my MAF. Thanks in advance

as of right now I dont ? do u think its possibly just nozzle position ? I moved it further up......and it surged less.......ive read that surging means that its too rich ? anyone had this problem before ? Im also in the process of buying an Altronics 02 alert. I dont think it has direct logging abilities but it should tell me if I'm too rich or not........anyone recommend a fairly priced way to log my a/f ratio ?

If it is a dry kit before the mas meter then it is relying on the meter to add the correct fuel to the motor. Maybe you are not getting a good reading off of the meter or your tank pressure could be low. I am not that great on dry kits but maybe try cleaning off your meter and trying it again.

yep its a dry kit and its spraying about 5 inches before the MAF......what should i clean it with......I just removed the screen inside like i was instructed to before I installed the kit. The engine runs great when its not on the spray so I know its not a spark plug or the wires. The more I moved the nozzle away(up....so not directly pointing at the MAF) the less it surged......but it still did........would u think its just nozzle adjustment ?

all the above suggestions are good BUT...start with the easy/obvious thing. Make a small jumper wire to groud out the FPSS. SOMetimes when this thing is adjusted improperly, it will cause a surging because its allowing power to the solenoids and sometimes taking it away if the FPSS thinks the presure is dropping. Try this first. Just a 2 inch piece of wire, and attach it to the two screw ends of the FPSS to make it an open circuit all the time.
