Ok I got bought a NOS system for christmas Just had to do it. Any way it is a single nozzle shot with a 100 shot nozzle. I put it in..no leaks or anything in the lines. Here is my problem...I don't feel any hp gain when I do it. I don't really get why, I should feel a 100 shot in 2nd or 3rd gear but I don't. Like I said before, no leaks, I went through the fire wall, only hard part was drilling the cam cover. the nozzle hole is a perfect fit. Can anybody help on why I would not feel it...all the presure gauges are fine as I said before..and I am 99% sure that their are no leaks when I hit the button. Thanks. bah I thought I read a better write up before that was longer and funnier.
