How much noiser are the walbros than the stockers? I mean if you had just a TBE and flash on your car and converted it to just a catback and flash for servicing, would the dealer be able to hear the aftermarket fuel pump?

And I dont think turbotrix requires a fuel pump for just a TBE and flash, though I could be wrong.

 

I remember reading a dynoflash post where Al says custom tunes wont require a fuel pump but is highly recommended. A mail in flash however a pump is required on the 8 or he wont do it.

 

I've had my pump for a month now and so far it isn't any noisier than stock. In fact No one would even notice its there right now.

 

I hear my pump from time to time as a little whining in the back seat. Nothing too loud though. It's actually louder outside the car.

 

thanks guys!
