    Gauge supply split/cracked, bad connection, sticking gauge (e.g. Plasma Dial face on std. gauge)?

    does the 2.0 16v unit run at a lower pressure than the small 1.4 GT motor though? as a road car i know the smaller engined FIATs ran relatively high bost pressures compared to other turbo cars of that period.

    that might be one reason for a lower reading than youd expect to see on the standard GT boost gauge. if it feels blinding then maybe its giving its best just that it registers lower down on your gauge.

    The workshop manual states a max. of 1.05 Bar for the 16VT, but I'm unsure if that's the standard "controlled maximum".
