Will the stock ecu compisate fuel at 10psi (stock turbo), or do i have to get a fuel controller at that stage?

 

10psi is pushing the limits for no fuel management, plan on getting something to richen up the mixtures if you plan on pushing 10 or more psi.

 

i have a mbc layin around in my garage and am dieing to put it on...

 

You do not need a MBC to get 10psi out of a FC. All you have to do is put on an intake. That should bump it up to about 10psi. If you upgrade the exhaust with a cat back that would prob put you up to 12psi with creep problems.

Leave your MBC in the garage.

Edit - At least on the S5 TII

 

i have intake, and exhaust and i boost 5.5-6 solid. before, it would creep up to 10 so i looked at the vaccum lines off teh wastegate, and it had this jenky brass fitting in the middle of it. re-did the vaccum and now solid boost....but im slower =(

 

Wow, an open intake .... what kind of intake and exhaust?

pepboys $9 air filter on home depot plumbing intake, and Apex N1 catback with high flow cat

 

I find it amazing that you don't have anymore boost than what you have....what are you using to measure your boost?
