I know it produces the marble shaking sound but how audible is it? I really don't want to end up like bishiboy and i'm afraid my car might detonate because I pushed the car without tuning the injen intake but I am tuned for a cone filter by dynoflash so I figured it was alrite. I spiked to 22 psi at times but it was on 91 octane and in really cold weather, the 40's. thanks for all your responses.

 

pretty loud... there is some pinging that is very hard to hear which i'd recommend using some sort of data logger if your modding your car. But the louder it gets the later you are to fix it, and the more damage its doing.

 

One more thread that shows how crazy people are about flashes and tuning
here.
I have an idea: why don't you guys drive to your tuner every morning and tune it for the
day's weather?
Sorry for my sarcasm but I see you are barely modded and think about a 2nd flash
because you changed a *** filter.

European Evos get a fuel cut before anything happens. That's the only problem in cold
weather.

 

if it just an air intake changed, then there is no reason to worry abt detonation cause by the intake.
