Default boost question?

I finally got my car running well again.. Took out the 007 dv and put in a 710n, relized i was over
Tightening the 007 and it was not working properly (my friend justing pointed that out) any way i left the 710n in there untill I get a different DV, not a big fan of all the springs..

ok so here is the question, I have replaced alot of the vacum lines so i dont think i have a leak anywhere, Im holding 19psi which is what i should be holding, I spike to 21 or 22.. sometimes the needle on the boost gauge like vibrates up and down between 17-18 or 19psi really really fast, you cant feel any power flucuation just see it in the needle.. only happens once in a while.. what is that? and should i worry about it..

The needle fluttering could be a sign that you have a small kink somewhere if there are no leaks.. Either in your boost gauge line, or maybe one of the vac lines you replaced? idk.

Didnt you at one time talk about unstable idle with your stg. 3, and it being "normal"?? If so, and if you have a slightly fluttering idle, that would cause your vac #'s/needle to fluctuate.

yea once in a while i get a rough idle.. I think its really caused by switching back and forth between programs on the ECU, i have noticed if I do a throtle body adustment after i switch programs my idle is fine..

I was told its the injectors, I have bosch 440cc injectors and the ECU was tuned for Delphi 440cc injectors.. dont know why it makes a difference but it dose.. every question will really be answered when i rebuild the motor, still need to do the leakdown but the only thing that is going to do is make me angry...

BTW....Is there any way you can get a speedo video of your car going from, say, 0-100+mph?? Im sure it would be a real crowd pleaser... Is your clutch alright now?
