With CIS, GHL and a K27/HF (not 'S'), my car indicated .5 bar on the VDO @ 2500 RPM, which the dyno operator thought was "pretty useful".

In Real Life, I like the 915 to be spinning a bit quicker before I mash down hard on the gas pedal so I usually don't have enough load for that much boost that low...
'77 S with '78 930 power and a few other things.
