SAFC/Maft settings for 680's

[selmerguy]

I have been tuning alot latley and tring to get my car running good again with the stock 14b. I have my maft set for 680's and my idle tuned with the maft aswell. I had to lean it out a good bit to adjust for the dead time with the 680s. But I have it around 14.7:1 at idle. Anyway of my high throttle settings I still have it at between -40 and -35 % from 3000 rpm on. The car runs good and only knocks when it gets hot. This puts me around a 11.3:1 afr through boost. I am running 20 psi untill the turbo tuckers out(around 6000) I would not think that I would have to pull that much fuel with the Maft allready adjusting for the 680's. I am sure the injectors are fic 680's but that seems like alot of fuel to be pulling. Any ideas or comments?

walbro 255 and afpr. I used MMCD with the wideband mod. I think that 680s are to much for the 14b.
