Finally A Run With Nitrous But Inconsistent? Whats Wrong With These Times???

You definitely need to get a pressure guage for you nitrous bottle. Your wife probably won't kill you, as the guage is only $15-$20 and screws right onto the bottle with a T-connector, or under the hood by the nitrous solenoids. I guess this is a dry system you are running, kit#5115? You did retard your timing down to around 8 degrees BTDC before the nitrous run, right? Who installed the system? Did you? You can get a under the hood fuel pressure guage (again, fairly cheap...maybe $30??) that screws right into the fuel line on the passenger side of the engine compartment, where the stock Schraeder valve is. I don't remember the exact details because it's been a while since I've done it...but you can test your NOS system to make sure it is working properly and that your fuel system is boosting the fuel pressure up to the desired 80-85psi. The NOS techline can walk you through the test if you don't have the manual that came with the kit. The test instructions are in the manual if you still have that though. Do you still have your stock fuel pump? If you do, the stock pump doesn't flow enough volume to boost the fuel pressure up that high. Just some things to think about. Let us know if you figure this thing out.
