be nice to compare 3 runs
total fuel quantity , revs , boost actual , maf actual
total fuel quantity , revs , boost actual , maf voltage
unplug maf and repeat log
total fuel quantity , revs , boost actual , maf actual(ecu might give a calculated maf value)
see if IQ drastically increases over first and second logs, and also see if it feels any less laggy with maf unplugged
try to keep the logs on same stretch of road and similar manor , much easier to compare like for like after then.
as stated above the logs need to be (if safe conditions) select 3rd or 4th, straight road and floor throttle from below 2000revs up to 4000 revs or at least in the area your struggling
so 1700ish maybe unless its going to load clutch dmf too much , again no idea if a 2.4 10v will pull from there ok.
then we need a 2.4 to compare against fuel wise
appologies if following info is wrong for your car(no idea)
if your car has the same vac pump as the later 16v i measured values around -950mbar at the outlet from pump(id expect at least - 700mbar due to values required at actuator, minius leaks etc)
and if the turbo actuator is similar design to the 16v it should visably start to move off the rest pin around -100 or less and should have reached the stop screw at around -600mbar.
and at idle 75% vnt duty the actuator should be getting around -600mbar(max spool position pulled up to stop screw)
a turbo specialist or main dealer , or anyone with a e-manual may be able to confirm the exact vacuum values for your model turbo, and the garage
you and hugh myles in a similar thread on here may be able to work together on data and logs if the engines are similar
