Whoa.. Finaly able to post. (A boost question)
Hi everybody.
I am new here, was trying to post or reply for quite a while now. For some reason,
I couldn't. Anyway.
My 03 wasn't going past .8 MPa no matter what. The only way I could go to 1MPa is when I plugged in Perrin MBC.... I notice people saying that it's not a good idea,
but, I just wanted to see what happens. O, and the turbo spools up much faster now.??
Here is what I have so far:
STI intercoller
Perrin Y-pipe and inlet hose
Perrin MBC
Perrin down pipe
Mad Dad 3" mated to STI muffler.
Up untill I installed MBC, all those didn't make big difference, exept sound.
Any Ideas, suggestions?

Just wanted to know how come MBC made my tubo spool faster?
I spoke with a tech at RallySpec, and he said that MBC for WRX with stock turbo is a very bad idea as it tends to keep constant boost level through RPM.
I took it off and now can't get past 0.5MPa with boost comming in at 3000 RPM
I reset ECU this mornig, wil see what happens.

I am keeping boost under 14psi. The thing is with MBC I have much faster spoolup.
And because my rex is AT it rarely goes over 4500rpm only when I push it very hard mostly on highway enter ramps.
I am planning on ecu tune soon, posted a question on a new thread so please respond to that. https://www.i-club.com/forums/engine-management-66/ecutech-reflash-vs-cobb-acessport-104646/
I need more info
