Looking for a Fitech master to solve a tune

Hi, I'm trying to tune my Fitech and having a hard time getting rid of the rich condition I have just after WOT.
I'm attaching the log file together with a graph I did.
(I added some color to the AFR column to highlight where the rich and than lean spot is).

Hope you guys can direct me to the right direction.

You need to play with your Accel pump/ Fast Accel settings, start lowering your Fast Accel number in increments of 10 and see what effect it has. Are you getting a bog?

If you look at the graph you are sending too much fuel at first and then you are getting a lean bump as it corrects, I am more worried about the lean portion. Lowering the amount of squirt on a fast WOT will minimize the peaks on both sides.
