Maft Pro Tuning question

I have been trying to tune my car well with my maft pro and have run into an issue.

When I first floor it, the tranny downshifts and the turbo spools to 1 bar. For about 3 seconds it runs at about (13-14ish I know this is very lean for boost) then it goes to the 11 ratio I am looking for. I cannot tune around this 3 seconds of lean running, as when I add fuel to those RPM ranges it will cause the 11 to become less than 10 after the 3 seconds.

I am wondering if anyone has had a similar issue?
