I have no problems with a K&N FIPK but then I have an F&B TB instead of a
Fastman. I don't know what the differences are but I know there's no
vibration. The only time I've ever had a vibration problem was one of my
headers being too close to the transmission case.

Subject: DML: Help!! Get rid of the Z-tube??
hey guys, i have quite a quandry on my hands. i am having the gas pedal
vibration problem that some seem to get after installing an intake and
new/ported TB. it's serious enough to where i know it should be fixed, but i
am not sure how i wanna fix it.
i feel fairly confident that the problem can be resolved by going back to
the stock airhat that has the resonator on it, but that would mean getitng
rid of my Z-tube. the dyno doesnt lie, and i know it helped out in the
power. but, i know i want to keep the Fastman TB, so that means finding a
fix somewhere else.
Dan (the Fastman) suggested putting a little piece of sheet metal in the
Z-tube perpendicular to the TB butterfly to help create some turbulence and
help cancel/dampen the harmonics to where the vibration lessens. however, he
said he cant guarantee that it would completely resolve the vibration. his
idea was similar to what Bernd posted a while back.
my other options would be to send back the Z-tube and exchange it for a
Stage II. or, i could go back to the stock setup with a drop-in K&N, minus
that oddly directed airhorn and a larger opening in the front of the airbox.
so help me out PLZ! i wanna make the best decision that will produce the
most power while at the same time getting rid of the vibration. i only have
a couple days left to my 30 days on the Z-tube and i'm definitely keeping
the TB. any help would be greatly appreciated.
