Re: (aks98prelude)
2k is too low. youll need 2 msd pills ,open at 3k and close at 7500
you will also need (if you havent already gotten) a bottle heater and a nitrous pressure gauge. NX recommends to spray between 1050-1150 psi but ive found that to still dump too much fuel. warm it up to 1200psi. run the pill sizes NX recommends at first. do not modify the pills until you are either on a dyno or running a wideband on the street. when tuning shot sizes for proper a/f mixture size fuel pills down in small increments. do not attemp to tune a/f by increasing nitrous pill size. (start rich pull back fuel to tune)
some say you do not need to pull timing some say you do. personally ive noticed anything greater than 50 requires some timing retard.
hope this helps
Oh yea, if you need the nitrous pressure gauge i have a brand new NOS one PM me if you are interested.

Thanks guys... Silverlude i got the pressure gauge and pretty much all the accessories with it minus the auto bottle opener... So i should be good... I just took my car in and dropped it off for everything to get installed.... I just bought a vtec controller so maybe ill be able to cut a little bit more off my times... If you guys know anything else it would be muchly appreciated... I am a noob when it come to nitrous and dont know too much about the whole air/fuel ratio and how that works with nitrous... let me know thanks again

the vafc will give you some control of your injectors. this will not help you tune fuel for the nitrous shot since you have a wet kit and spray extra fuel via a fuel solenoid. dyno hand post some charts. youll get some feed back on your fuel conditions.
