I had a length of 6mm pipe going from the dump valve to the inlet manifold, it may have been off during the video, it ran the same when it was on although the dump valve sounded different, as if it was open when it sholdnt be.
When it went through a wee stage of running at high revs the dv was open the whole time.
From what i understand of the management system it takes a position reading from the distributor, i could be wrong tho.
Could it be over or underfueling due to a mismatch of efi and mfi parts? pump being too strong/weak for efi fuel rail/regulator?
The management thing powers the injectors but not the pump. This comes on when i turn the key.
