Is it standard with the OE EBV connected?

There could be a few causes,

Its the same characteristics as mine had when a coil pack was starting to break-down and fail for instance.

If you still have the standard EBV they have a habit of going South, mine did when I fitted a Gtec1 in 2005, best get a boost controller or a BCV especially if modified. I seem to remember I would get fluctuating revs/or undulating waves of power when on full chat. The BCV and boost gauge sorted it and it has been fine for 14 years.
