Are those two butterfly's the ones you recommend removing as well?
I'm going through this process at the moment-fitting boost & EGT gauges, EGR blank, Dawes valve, manual boost tap.

As per the question above, what is the go with these butterflies on the ZD30? There seems to be conflicting info on whether to remove them... I assume the smaller on closes off as the EGR is opened, what does the larger one do? Do both get removed?
