Without a window switch, which cuts the nitrous on and off at a specific RPM range, you will be spraying below 2,800 RPM's and during shifts. The "during shifts" part may be true or false depending on how you set it up. Some kits see the TB close a little during shifts and kill the nitrous until the TB is opened back up and the correct voltage is reached. Other kits that run off the gas pedal will receive a full 5 volts during shifts, so the nitrous and fuel will be flowing full steam even though the RPM's are dropping like flies.

Moreover, when you get to the point where you try to program the NMU (or equivalent) off the TB, shoot me a PM and I'll walk you through it. It's simple in theory, but far from it on our cars.
