Hi!
MY car runs really great now after a lot of chip tuning but the tb have a wissling sound when I am hitting the trottle in the middle rpm.
I am running whith a drop open aircleaner now but i am wating for a non drop so I can finish my ultimate tb mods.
So I still have that gold metal ring on the tb.
Could that be my trubble.
Thanks
Anders

 

Its just the engine sucking in air. I think it's a pretty cool sound if you ask me.

 

Ok!
But do you think it will stop whith a new aircleaner and how big difference will it bee whith the stock spacer gold ring gone?
Do you think I can add some more fuel to the tb after that?

 

The sound will always be there. You can just hear it now because of the open air element. The new air clearner might change the tone but it will still be there. As far a fuel goes its not yet necessary to adjust the fuel pressure. The ECM can componsate for whatever additional air you are getting into the motor. Usually the ECM can componsate all the way through a full exhaust. Past that and you're going to need some chip tuning.
