It could just be the gauge its self... my old one used to flutter. I got this isspro and it does not anymore...
Where is it tapped into and what type of gauge? What type of readings too?

my search ability just failed me, but I recalled some guys having the same problem and they fixed it by filling in the tee (just the guage leg) with JB weld and then dilling it out with a tiny bit and that dampened the flutter.

That works good or you can get a fish tank air line adjuster brass thingy and dial it closed to reduce the flutter as well.....

tell me more about this fish filter dial-o-matic outfit. i have the same problem. it has driven me crazy. about 14 or so on up it starts bouncing. tops out bouncing between 19-23.... very annoying i was thinking of making some type of hydraulic damper but that sounds much easier

this isspro gauge has been installed for 2 years and just recently started doing this...I have not looked at it but will this week.
With the performance issues wouldn't you think it was in the turbo itself?

The easiest tthing to do first is to pull the intake hose off and inspect feel for play, look for dusting.

inspect the turbo. check for play, dusting, the o-ring where the compressor outet meets the intake "Y", lower y boots. also check the map line to make sure there are no splits in it.
When you say performance issues how bad are we talking? How much boost is he building? excessive smoke?
