help with n249 vavle

[mkturbo3]

Quick question when bypassing the n249 valve you are suppose to have a T running from the DV hose to the front of the manifold and one hose to the n249 valve, and have the other to F hose ? is that correct? Also what about the other valve? i have one running to the EGR valve and the other 2 looped is that correct ? i just installed a forge 004 and now it is running like crap and back firing when off throttle, i read 01+ would be fine running a 004. right now i have my n249 looped and the other port connected to the F hose and running the DV hose straight to the front of the manifold. Is that why its running like crap cause i dont have T'd to a vaccum source?

Just take the n249 out of the equation.

so what would i do with the F hose ? plug them and plug both n249 valves

There is only 1 N249 valve. It controls the DV. The other solenoid valve is the N112. It controls the combi valve for the Secondary Air Injection. That is important for keeping your Check Engine Light off (and saving the earth...apparently).

When bypassing the n249 valve, the steps are:

1 - Disconnect line from Manifold to N249 and the manifold end (small port at very front of manifold).
2 - Disconnect line from DV to N249 at the N249 end.
3 - Connect the line from the DV directly to the manifold, using the small front port from Step 1.
4 - Take the end of the line from step 1 and "loop" it to the newly opened port on the N249 (from step 2).
5 - Make sure all line connections are tight with a zip tie or other suitable clamp.
