But a gust of wind blows into the system and spikes the volts and your foot isn't pressing on the throttle hard enough, the system thinks you are pushing harder and adds fuel because of the increased air the MAF saw. The car drives like **** and sputters and hiccups. You can test it by running the car in the driveway and blowing air into the setup from outside the bumper with a air compressor. Needless to say I had to block off the inlet in the bumper.

I wouldn't go SRI unless you vent the hood and bumper inlets need to be off to the sides of the filters unless you have a CAI setup like me or stillen.
