Defi Boost Gauge Install

I have a Greddy 60mm Electronic w/ peak hold and warning Boost Gauge. My levels fluctuate as well.... it's not bothersome for me... however, they did include a small restrictor that could be placed in the supplied 'T' that is supposed to stop the fluctuations....... didn't you get something like this?

Edit: Just to clear any confusion...... I didn't use the restrictor, that's why my boost continues to waver.

Well, it seems to me that there are a number of possibilities.
1. The boost level is fluctuating. If this were true, I would expected to read about it on this and other boards and/or feel (seat of pants)/hear (turbo whine or rpm fluctuations /see (tach fluctuations) the fluctuations.
2. The boost is steady, but there is an aberration in the way the vacuum is transmitted down the vacuum hose. That is to say, the change in pressure does not progress linearly, but instead has something like a wave form that it follows, or there is a rebound effect, or the hose deforms or some other abnormality.
3. The sensor is just too sensitive and detects minute changes that exist, but do not impact performance.
4. I have screwed up the installation.
I'm trying to get input from others, in order to rule out as many of the possibilities as possible (or have someone suggest a fix)

Blue, yours posted while I was responding to the one befroe yours. Mine did not come with a restrictor. I am trying to find a restrictor for a 1/8" ID vacuum line. No luck so far, but it is my next best hope for a fix. How much does your gauge fluctuate?

the T that you spliced into the vacume line off the BOV. i need one of those and i need it to work with the fitting that come with the autometer boost gauge. was it just a standard T that had three threaded ends, and did you just get a 1/4 to 1/8 end and screw it on for the smaller line?????

It was a 1/4" x 1/4" x 1/4" from Autozone or Discount Auto Parts. It was a standard T with three barbed ends. I don't know what fitting comes with the autometer boost gauge. The 1/4" to 1/8" reducer had barbed ends also.

i know these seems like stupid questions, but were the barbed ends the type that screw out of the block that holds the T together???
what i need is a 1/4 x ???thread x 1/4 so i can thread the press fitting end from the autometer gauge to it. i was hoping that i could find a T fitting block and then get the three ends i needed and screw them into it.
