I am guessing again, but when the fuel pressure is
varying suddently when adjusting it, the idle could
be a little more rough until the computer recalculate
its A/F ratio table. You should ask this to someone
that has more experience but i could be right.
The idle has nothing to do with the perfomance at
WOT. I would go to the track to adjust everything
or have a dyno session.
