silver74vette 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.

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.
