Sounds like something has gone wrong
You say it was tuned fine last year
Usually one gets his Closed Loop tune fairly close
then
He goes to work on the Open Loop or WOT tune
Not doing it in that order just makes for double work
cause your inj values effect the Open Loop tune you
just got done with when you get around to tuning
for Closed Loop
Briefly ... the fuel tables in our pcm's call for high 11's to 1
In a nutshell ... For WOT fuel tuning
I work with the Open Loop only part of the maf curve
I set my fuel table a bit fat all across the rpm range
I then adjust the maf curve to achieve the commanded ratio seen
on my wb from the table
That allows me to easily change my ratio with fuel table values
Since you are seeing 8.00 to 1.00
Something ... Somewhere ... has got to have gone wrong
for you to be seeing that fat of a mixture
or
Your wb is outta whack
