WRX 1993 not boosting smoothly

I have an imported 1993 WRX. standard apart from decat downpipe and 3.5" system.

When on boost it does not pull smoothly and stutters all the way through . It is way down on power and does not surge forward. The problem seems to be intermittent.

Coil packs have been changed, Lamda in manifold is brand new and Air mass been changed but still does it. It also does approx 180 miles to a tank of super...

Any ideas anyone!!? CHEERS
