Zleh scooby noise (misfire) at 2k revs

[wkdkris]

Zleh corsa makes a really loud scooby impreza like noise under full throttle from 2k rpm untill it picks up. Whats causing this?

Got all vxr parts obv...
3" de-cat from back of turbo
large top hat
3" hard boost pipes with FMIC
Bailey D36D DV
Forge OE DV blanking plate
Bypassed rear BCS

Just fitted a new set of genuine VXR plugs, made no diff.
Also boost seems a bit low at 0.6 Bar (8.7PSI) Spiking to 1.5 Bar

Coil pack? Crank sensor? Trial & error with stuff like this, i've just had it on my let, timing had slipped, worth a look!
