Are you using the stock MAF?

That should solve your problem. Otherwise it's time for a MAF upgrade.
Stay away from the FMU. Imagine going up hill, partial throttle while boosting, high load.
The FMU notices the boost and dumps so much fuel.
My AFRs were around 9.0 just going up hill
I ditched that and went with an aeromotive fpr

I'm using NGK Iridium IX.
It does hold AFR pretty good but jumps from lean to rich then stoich on first start up. Then when reaching boost it gets rich then leans out immediately. Working my way up to boost at lower RPMs it is pretty rich too.

Ok I just bought some CRC Mass Air Flow Sensor Cleaner and it says on the back, "DO NOT use on vehicles witha Karman-Vortex air flow sensor, e.g. Toyota Supra Turbos, Mitsubishi's and most Lexus vehicles." Are you sure it's safe to use it then?
As far as the tune, I still need to work it out a bit but I have the afr's hit 11.5 under boost and slowly drop to 10.8, after I adjusted the maf scaling and the fuel map a bit. Still working on it though.
