btw, recently I put AFR gauge on my car and it showed 10:1~10:8

Too rich than I expected, so I reduced the PE numbers to 1.22 on the all rev and it made 10.8~11.5 :1 on the actually AFR gauge.
Furthermore , my rail pressure was back to 13Mpa from 11Mpa range (from 1600 to 1900 PSI). It is not enough, but better than before,.

Not bad result. I believe that I made my injectors sprayed the way too much due to some mis-calibration like MAF and it triggered the lack of fuel.



Are there any other guys having Whipple and checked AFR with the stock flash?
My wide band is in the mail. I'll post up some numbers once I get it installed.
