Used my hptuners vcm scanner this time..

fuel pump trim short term 1.00-1.01
fuel pump trim long term 1.21
(at idle)

commanded duty cycle 30% at idle
32% free revving at 2500rpms.

So apparently mine went down a little bit..?
Perhaps it is compensating for environmental factors? (as well as pump variance)
