Yes it is.  I would think that without first addressing the airflow issues
in the WBX heads the increase in fuel flow will not gain much of power.

I think Boston Bob and Robert Lilley have this one covered.  The WBX can be
made more powerful by addressing the inefficiencies inherent to any motor
design, but in some ways unique to the flat-4 engine.  By increasing the
motor's efficiency it never really works 'harder', it just has more muscle
to do the work. Although this is an over-simplification of the solution,
Robert Lilley and Boston Bob many educational posts are available in the
archives for our retrieval.
