I was having all sorts of issues with the tuning trying to sort out a stumble at cruise. I finally suspected the fuel pump and replaced it together with a new fuel pressure gauge. Made a world of difference.
Have also managed to solve the hesitation at 1900 rpm by raising the maf diag error threshold from 45 g/s to 100 g/s.
Time to get back to tuning at WOT. Certainly getting a good fuel supply now and no knock counts in sight.
I have a LM-2 Innovate Motorsports wideband sensor and datalogger installed on my right exhaust bank.

Got my first afr datalog from my LM-2 wideband. Note the heavy acceleration episode in the centre of screen. Seems to dip into the high 10s on wot. Maybe a bit rich.
