Can CL to OL Delay cause me to run lean in transition to boost?

Can CL to OL Delay Cause Me To Run Lean During Boost For 1 to 2 Secs?

That's the million dollar question. Its like no matter what I do in the "Primary Open Loop Fuelling" map I'm running lean for a second or two in WOT (transition from cruising to WOT in a low gear).

Isn't it true if your MAF scaling is good, Fuel scaling is good then the ECU uses the "Primary Open Loop Fueling" map to target your A/F in open loop? Can it be that there is such a delay that I run lean before the ECU says everything is good then transitions to WOT?

If that's the case, what tables do I have to zero out? I've been reading around and its flying over my brain and making me go cross eyed.
