i would concentrate on investigating the recuirc valve if you havent done already..... lost boost that way is more or less undetectable & unhearable.....
hi, i recently changed a good recirc for a recirc with a massive split in the diaphram because i liked the chopping sound when the un recirculated air was trying to stop the compressor wheel.
there was no drop in boost pressure at all with the damaged recirc in place.
a split in the recirc to inlet manifold hose could bleed boost pressure off but id have thought this would happen consistantly rather than here and there.
meter of 4mm bore fuel line and 5 minutes work eliminates the possibility of this.
