If this is the wrong forum please move. I have installed a Devils Own stage 1 meth kit on my supercharged 98 Cobra. I cannot run the car in boost right now due to needing it dyno tuned, but I want to see if the meth system is working before I go to the tuner. The system is boost referenced and I have it set to kick on at 2psi. In theory, could I just turn the ignition on, blow into the vacuum line and listen for the pump to come on? I dont want to waste a trip to get it tuned and not have the meth working. Thanks.
