i got a terrible fluttering sound on my evo x after i installed an injen intake ...
dear god any genius can help a chicken to fix it up????? PLZ!!!!!!!!!:confuse d:

 

Check all your hoses and connections. Make sure you reconnected your BOV correctly.

 

Did you change to a new BOV when you installed the intake?

Chances are this is not "compressor surge." The stock airbox and intake tubing is plastic, creating some noise dampening. When you replace all the factory plastic with metal tubing, the car sounds, both good and bad come to life.

When I first installed my ETS intake, I had a fluttering I was sure was compressor surge. After taking it to my tuner and chatting about it, I now understand the noise isn't harmful, and is just more audible because of the aftermarket intake.

Just to be safe, I'd take the car to a reputable tuner and have them listen to the noise.

 

thanks for ur answer..i didnt install an aftermarket bov and yes thats flutter after i left the gas ans on low rmp...my frd told me its gonna be.fixed after iget a intercooler and whole pipe ...

 

I'd venture to say an intercooler and solid piping will have no effect on the fluttering noise. See a real tuner who knows Evos. The only thing that may affect the noise is a tune.
