Default confused???

so i dynoed my 03 gt today. it has a 125 wet shot. i did 2 pulls and when i was done, the guy informed my that my car was running a bit lean at lower rpms, and then richend up up top. to be exact, it was 13.0 when i started at 3000 rpms, and around 10.5 when i let off around5900 rpms.he seems to think that its cause im still running on my stock fuel pump? anyways, i have a 255 lpm fuel pump on the way. then he tells me that once i get to pump on that it would be a goood idea to come back and redyno it cause he states it will be running to rich. thats the part i dont understand. does that sound correct?
