Nice car. Bit of a different sound with those headers.
I noticed that you haven't unplugged the secondary's bypass valve. This could be causing the CEL as it will be venting all boost below 4000rpm creating uneven pressure build up between each turbo. The differential pressure sensor will notice this and throw out a code. If this is the case it will be seriously hampering performance too. I would disconnect the vac line from the black box and plug it up, then tee the bypass valve into the blow off valve coming off the intercooler.

Hi! Mr.Aaron! i do everything already what you suggest and plus i have the SYMS RACING ECU,and i have a chat with SYSMS RACING,they told me that to un plug the diferential pressure sensor also.
the car is running fine.

Best regards

the cel code is on is because the unplug of the diferential pressure sensor,and with the SYMS RACING ecu,i also have boost cut at 1.1 bar,full boost at 5000 rpm,speed limit can over 180km/h,fuel consumption,better then standard.

and in the syms racing site also say is normal after manifold installation the engine light will on,and the diferential pressure sensor need to be disconet.

Ahh. All good then. Didn't realise you were also using their ecu. Just out of curiosty, I assume the syms ecu keeps this bypass valve closed then?
What is it like to drive under 5000rpm? Does it feel slow and sluggish?

[TTimpreza]

for normally drive up shift gears,4000 to 4500 will be needed,is like a natural aapirated car,after 5000 is a turbo car,i call it late spool up,and something very special is the tacho meter and the boost meter they run almost the same speed,very linear.

i want to do a better video for you!

this is very fresh video when just after start,not have good setup yet http://www.facebook.com/home.php#!/video/video.php?v=448017187122&comments

[TTimpreza]

yes the bypass valve need to be close.

Hey guys im new to this website and new to my 2001 Legacy B4. I just put on my SYMS equal length manifold on. I do not know how to block off the secondary BOV and disable the Pressure line. Can anyone walk me through this with some pictures or a description on how to do it? This would be much appreciated.

[SubieDubie]

Alright so i closed off the secondary bov capped the two lines and disconnected line 1 and line 21 the pressure sensor. but now im not getting blow off from the primary side. Plus im only getting .6 boost? Any regards

With the installation of the SYMS parallel headers this will create a 'split' twin scroll.(with none equal turbos)
1.To keep the IACV open Line No:1 from solenoid box is removed and capped.
2.Both solenoids No: 5 and 6 have been capped as you have removed the ECV and its actuator
3.To keep the Supercharger Pressure Relief Valve (SPRV) closed remove No:8 from the solenoid box and T it off with No:12 (connected to the manifold pressure)
4.Keep Line 21 connected and remove Line 22 from the SPRV and block that nipple off.
5.Connect Line 22 to solenoid No:8

[SubieDubie]

Thats exactly what i needed. good day good day.

[SubieDubie]

That black box of doom

[zanzarah]

Note:
The SPRV can be removed as it is now functionally redundant. Plus no need to do 3.
Once removed you will need to plug the intake port and cap the compressor stack/chimney.

Hi, Zanzarah! U install in u car 2 TD04S, and its`s work like biturbo?  Where i may reed about it? Maybe in u blog or somthing? I drive Subaru Legacy 2.0 T/T. Install the Syms Rasing ecxaust 

thanks to you)) and all works. I want stay on biturbo, but I want change stock turbos.
