74-75% is maximum for boost solenoid on fes , thats max spool position
a quick blast on the throttle may see it dip into the 60,s% cant remember
driving you could see anything down to 19.99% which is vanes fully open min spool position, and normal driving with boost expect 30-50% range.
but yes vnt is controlled off a ecu map revs, injected fuel and required boost = vnt %
for injector correction i thought the 0.9 was at idle as a guide for good values or even 0.7 for later jtdm
do a good scan when engine at max temp at idle and log values , then try with engine off removing and cleaning the injector connection plugs(electrical contact cleaner spray or similar) and recheck values.
then try a good dose of injector cleaner for a tank of fuel and then log again, if you still have values above 2 maybe an issue but if engine idles smooth and sounds ok dont stress about it if that value gets up towards 5.0 theres something to worry about.
i log all correction values at idle engine hot as its easier to repeat well.
