When I installed the Z-tube I never did experienced this problem.
Where is the vibration occurring and what RPM range is the resonation or
vibration is being felt, Adam?

Subject: DML: Re: Help!! Get rid of the Z-tube??
just to let you guys know, i installed the stock intake last night and still
had the vibration. so it's either always been there and i never looked for
it and therefore didnt notice it. or, it's all the extra airflow from the
TB, which in one sense is cool since it's obviously flowing more.
either way, i am keeping both the Z-tube and the new TB. i bought some stuff
last night to make a little vortex wing (or whatever it should be called)
inside the tube so i might get to that this weekend. and even if it doesnt
completely fix it, i'll not worry about it...
thanks to all who offered suggestions!
