I finally received the GS 3 ports EBCS, and it doesn’t solved the problem. I’m running it on 2 ports of course. A few things I noticed while replacing the EBCS: There is no restrictor pill on the hoses between the IWG and EBCS, and between EBCS and turbo inlet. I mention this because I...

Alright, so while I wait for the GS EBCS I decided to do easy stuff of checking and cleaning the sensors which are accessible. Cleaned the MAF sensor. Tighten every clamps. Cleaned the throttle body. Cleaned the MAP sensor. Founded out the hose between head and intake was torn and fixed...

Hello, I need some opinion about the use of CS Intake Manifold on a stock turbo car. I figured maybe this is a question a Mazdaspeed3 owners can answer. Since I am planning on cleaning the intake valve, I figured this is a good time to install CS injector seal and DM EGR block kit. Seeing that...

Alright I placed an order for GS 3-ports EBCS. I quite like the idea of placing it farther away from scorching heat. But yeah, it is a very strange problem because the car drives nice and makes good boost. Then again I am always above 3000rpm whenever I want to WOT. Hopefully this sorts it out...

Well, I guess I may as well change the EBCS to 3 port and run on 2 port to see if it fix the issue. Which plug and play 3 port EBCS is recommended?

Hello, I am wondering if anyone has seen a boost oscillation problem such as this: (3rd gear log) There is no vacuum leak that I can see from smoke test, and it is definitely not a tune issue as a different tune map also result in basically the exact same problem. And both tunes was done...
