Is this normal?

[Jerry@tx]

So recently i did the ccd mod and also removed the bottom air box from my air filter. So everytime i let off the throttle i can hear air pushing back out of filter. When i floor it and let go it sounds like i have an blowoff valve. Is this normal?

[floorboy]

Yes, normal.... and kool.

Yes. It's called "turbo fart" these trucks do not have blow off valves so if you get an excess of pressure, it will back off through the turbo and make that woosh type noise.

at 00:54 he starts getting the truck to make the noise. Is this what you are experiencing? If it is, it's normal and a-okay
