Fat tune with moderate boost

[Timbuick]

Hi guys, iv'e noticed that my 02s are reading 800-830 when boost hits10-15lbs. I added 5% more WOT on the chip a while back for when i get into higher levels of boost, but I'm not running WOT when the tune fattens out a touch.
I'm running alky on Razors default setting.
F/P set at 43 as per TT chip requires.
Any way I can lean the car out just a little without going into lean zone?

There isn't any way to lean out the part throttle, that's all in the chip makers hands there.

What you're seeing for o2's at 10-15 lbs sounds about right, if you're on the throttle hard enough to build that much boost, A: the alcohol is spraying & B: the TPS is high enough that the car is "anticipating" you going WOT, so it has started dumping in more fuel

Furthermore, I'd rather be on the fat side vs lean any day.

OK, I did wonder how subtle the tune could be at part throttle. Guess I'll try WOT and see what happens. Usually I run out of road!

Thought i'd return to this. Had a quick WOT blast to pass a car and there is something 'wooly' about the tune at full throttle. No breaking up or anything drastic, just feels like it is too rich. Scanmaster showed 808 02s zero KR. Not exactly over rich is it?
Still pulls like a train when punched from low down.
