i had read another post last week describing how an svt poster drilled new holes into the fipk enabling him to retain the stock position of the maf.

i drilled new holes in my fipk to keep the stock location, then went to the dyno to see the results. i was curious to see what the a/f looked like, since many, not all, have reported a/f ratios going lean with the installation of the fipk. the reason most often given for this lean condition is the reposition of the maf to 12 o'clock.
my a/f looks like a bone stock cobra going off the chart pig rich @ upper rpm's
first run was the high @ 392. hp & 367 torque. car was hot when it went on the dyno
