Default ecutek with boost control Q

I'm buying a used 04 ecutek from a guy for a great deal, and my question is: do I need my stock manual boost control when I'm running it? The shop I had my engine mods done at threw away my stocky. I currently have a perrin manual BC. I'm a total noob when it comes to EM, cause I know nothing about it. Except a stage 3 is faster than a stage 2.

You want to run the stock boost controller. ECUtek remaps the boost values.

That sucks that your shop threw away $150 of your money. They should buy you a new one.

I dont know why they would. Its a subaru aftermarket shop, they probably kept it. My buddy however told me last night that the stock boost controller is built in. Hell I dont know what to believe, I should have just done it myself. God I hate being such a noob.

The guy I bought my ecutek from told me that I can run the manual boost controller with no problems. He had it tuned when he was running an electronic boost controller.

Now I'm running the ecutek with my perrin mbc between .6 - .8 bar. Which I've been told is a good level to run full throttle.

Can anyone with the knowledge help me out?

You *can* use an MBC set to ~1.0-1.1 bar (of whatever the ECU was tuned to) if you want. The problem is that you will still get some part throttle full boost situations which are bad.

Take a look in your engine bay. In front of the passenger side strut tower is a small black cover. Remove that and look down. If there is a small black "cube" with some hoses sticking out of it that is the factory boost controller solenoid.

Theres a hose line that splits with a T, just hanging there, I've never noticed it until now. So that must mean that they took it out? They wouldn't have thrown it away and did they even need to take it out in the first place? It probably could have been left there. Hummmmmm..... something smells fishy.

Take a picture and post it if you can. That line with a T is the factory boost control line from the turbo to the manifold most likely. Is there a line connected to the tube of the turbo inlet tube going right next to the coolant resevior?

I thought you were supposed to use a separate boost controller with the Ecutek? I was JUST about to buy and use the Apex'i Electronic Boost Control. Bad idea? I originally ported the wastegate because of boost creep after I installed an MBC. I took out the MBC but still have a ported wastegate so I'm running about 1 psi under stock. Any suggestions other than the EBC?

Here's some terminology for you.

Stock Boost Controller -- This would be your car's ECU. As your car's ECU is what is controlling the boost...therefore it is the boost controller. I'm assuming this is why your friend said its "built in."

Stock Boost Solenoid -- This is what you were referring to when you said "stock boost controller." It's the physical piece that resides in the engine bay that controls boost.

Sorry for my terrible definitions...wanted to make things easy on you.

In regards to whether to use an EBC/MBC with an ecutek reflash...some tuners say yes, some tuners say no. Personally I would stick with a perrin upgraded solenoid(should be out this week). It looks very promising. Btw, Bill@I-Speed is one tuner who is against boost controllers with the Ecutek reflash. Perhaps you could ask him why.

Thanks for all the help guys. I'm not too worried about it now. I do have some turbo spike at about 6k to redline; about 2 pounds more than what its supposed to be set at. After I get my uppipe in I'm taking my car to PDX tuning. The guys there can probably show me whats going on, and whats best for the wagon.


I wish I could take a digi pic of the dangling hoses, but my dinosaur of a camera cant take pics close enough to see what it is.
