I need all you nitrous guys...

Do I read right? It never performed right? What is you ignition setup? Did you inspect the plate carefully before you installed it? I use a fresh can of brake clean to flush both bars before you install it. This does two things, clears all the crud that might be int them, an shows if any of the holes are not flowing properly. There are lots of issues with holes not flowing in the bars. If it's NO2, the engine goes super rich and pops, farts, and smokes like mad. If it's fuel, the engine can go dangerously lean, and/or break stuff. Are you positive the red side is connected to the fuel solenoid, and the NO2 is connected to the blue? If you have them backwards, you may be flowing too much fuel..I'm not sure what the Sniper is sent out with for jets...
