Stock Induction pipe problem

[Hollow_83]

High i have an Ibiza Cupra 05 and i have a big problem with the stock induction pipe.My car is completely stock with the exception tha vagcom gives me very high nm about 29 and a lot of overboost 1.16.
The problem is that when i push my car hard with a 3rd gear or 4th gear from low revs to limit
it gives me the feeling that it loses pressure and my turbo sound is making pauses. Basically it gives the feeling that the induction pipe is get sucked.
Any ideas?Thanks in advance!!!

As Sisson mentioned can u explain more? When you say induction pipe is getting sucked, do you mean squashed? Like the one on the forge website?

Also induction pipe from where, bonnet to air box? maf to turbo?

And 1.16 isn't over boosting at all, mine has peaked at 1 bar, also vagcom isn't 100% accurate, take it with a pinch of salt.

My dealer said that my car stock boost should be 0.7 normal and 0.9 overboost and i see 0.9 normal and 1.16 overboost.In bar not psi.
Iam from greece.From maf to turbo.
You say it was picked at 1bar.
I dont get it what's the stock boost of an ibiza cupra.
I thought it was 0.7.
To mage it better for understanding when you have for example a third gear and make a full throttle you can hear your turbo ok?
I also hear my turbo but with pauses it's sounds like it's stop sucking air it feels like i step my foot off the gas petal but i don't.
