Default Boost Surging Issue - w/ Video

Hey guys,

Just today I noticed my car at WOT in 5th gear gets up to around 15 PSI and the flutters basically between 13-15 PSI. Very strange.

I was suspecting N75 Valve as I do have the updated TT225 DV installed. All vac lines have been replaced as well.

Any ideas?

Does it only do it in 5th gear? Any chance you can try a different N75? Sounds like a reasonable place to start.

I was just at the PnP today and coulda grabbed you one.

i'm kinda going out on a limb here but I think it might be the intake boot collapsing

Base: I will check if it does it only in fifth after work today, if it does, what do you think it could be? Also, I may have to go to the PnP and grab one. Cheap option to see if it is it.

Redline: What would be a good way to test this out? I'm sure its old and wore out though.

only way to test it out, besides putting a camera under your hood, is to buy an upgraded one and see if it fixes your issue.
