new logs.. cf still poor

new logs after fitting phenolic gasket.... note the poor maf readings, i unplugged the maf and the stuttering on low revs i was seeing dissapeared so id say maf is on its way.
only logs i could do as it started snowing...
quick one ontop of this, when i unplugged the maf the car started misfiring, vagcom codes were cylinder 1 and 2 random misfire
is this related to the maf or are the coils dying also.... could this explain my recent running lean on previous logs??
also note the logs were done 30mins after a 60 mile round trip so inlet temps a little higher than on a cold run, outside temp circa 2 degrees

maf officially knacked, run with unplugged, runs fine, hesitancy gone, hopefully this is the source of the leanness.
pipercross foam huge filter on the way, i know bill doesnt like these but backdraft recommend them, so ill be different and try it. it is fappin huge aswell.
should raise some more g/s.
finally getting somewhere on this, ill relog afterwards.
now for the abs problem and the whining noise and hopefully she will be there.

new logs after pipercross foam filter and oil change.....
whining noise has subsided slightly after the service, picks up well now, feels quick....
outside temp slightly warmer today at 5 degrees.
also reversed dv now..

yeah, literally just put the filter on, looking at a air feed to it next...
gonna have to go to will i think on the lean fuelling.
running out of things to do now

mines strait onto the maf for now, waiting on a silicon pipe to straiten the airflow out a bit, may add a bit more.
ill reset the ecu to clear the learned maf values and try again from there.

some more logs done this morning
that was with 5% fuelling on inc load added
this is with 10% added on increasing load
cfs much much better
tried adding some timing just 1.5 degree added gave this
so i put back to 0 timing advance
looks better to me with the fuelling added, cf dropped with 10%.... but does fuelling look right??
comments welcome

looks better to me with the fuelling added, cf dropped with 10%.... but does fuelling look right??

fuelign looks better to me.. better to see 0.8xx under boost once spooled.
your first log did'nt have fueling tho
your first log did'nt have fueling tho
yeah sorry bill, added 5% to see cfs, they stayed the same so added 10 then logged fuelling.
fuelling look right now or??
fuelling look right now or??
when i added 10% bill it went to 0.9xx the log under where it sees 0.8xx is with timing and duelling added
