Since I installed a cold air intake I hear my turbo surge (stututu) when letting off gas.

I just changed the diverter valve for a new one and I still get that exact same surge noise.

Any ideas??

If it happen to anyone else Ive putted a lower spring rate and now no more surge

Ensure you have no vac leaks especially between your n75 valve and your wastegate

Why is that?

I reread your last message if you put a lower spring rate spring in the spring probably isn’t strong enough to hold the diagram or whatever gate you are using shut

I will look if it leaks and look at the n75.
If it interest you au will tell you what was the problem

You can also hook your diverter valve to compressor at around 10-15psi and see if it’s leaking
