butterfly mod disables the egr butterfly. which is one of the duties the big butterfly does.
needs to be done when you block the egr off.
the swirl butterfly is the smaller butterfly on one half of the intake. disabling that (unplug it!) lets more air flow in the lower rpm's.
Ok tweak now I'm confused at what iv done. I put a plate at the top where the manifold is and I disconnect some pipes on top according to ur thread with the photos so what have I done.
I don't remember unpluging anything as well. All I did was rearrange the small vacuum hoses as per the diagram.... Have I missed doing something too ?
sounds like you have blocked egr and done buterfly mod (egr butterfly).
swirl valve is a separate thing which is why theres not much of a write up on it. easy enough to do, unplug the solenoid (brown one i think).
that just stops the swirl valve from closing and blocking off 1/2 the air flow in the low rpm's.
