Also I was thinking my waste gates aren't calibrated, 70k on them I don't blame em, so is there an easy way to do the front one ? I can get to the rear one, put a vacuum syringe to 6mmHG and make sure it's closes completely (that's what I read on n54tech)

You can easily get the rear one but no way to get the front unless you pull the turbos off or the whole engine.

The last thing would be your boost solenoids, if you can check them somehow, great, if not just buy one and replace the old one at a time, they're not very expensive.

i will look for leaks today, and i already bought new boost solenoids and replaced them with the old ones nothing really changed. im going to do logs to day just to make suer..
Ramadan Mubarak to you too bro!

If u don't wanna do a boost leak test, just runthe eengineaat idle and start spraying carb cleaner on the valve cover sides aaround the block, if rpm increases it's sucking in air ... my boost leak was at a very weird place on the valve cover, I had a broken bolt that caused leak from

i will give it a try today, is the rpm increasing will noticeable?
and i think one of the Diverter Valves is not working right, is there any idea to bypass one of them?
example: unplug one side and use 1" plugs and use one vacuum line to the another side instead of the T? or its not good for the car?

update:

when i was doing the leak test i got a big leaking coming from behind the engine, after doing after doing some research i think the leaking is from the turbo inlet pipe:


any suggestions how to fix it?

Vargas makes a rear inlet bracket you can purchase, it will hold the inlet on the rear turbo. It doesn't come with a bracket from the factory.

That has nothing to do with a boost leak even if it is leaking. That just means you're taking in a little unfiltered air. That's not part of the pressurized system

I put an Oring on mine, still its not supposed to be compressed under pressure, thats intake, best is to pressure from before FMIC (passenger side)
