Can you explain how a pump is related to the IDC?
Unless you made a change in the tune.

Especially with his Speed Density tune... There is no direct correlation except when in closed loop, and even then, it wouldn't go to that extreme...

pump going bad and running out of fuel causing the injectors to work harder??
if thats not possible i cant explain it though... a/f leaned way out and the motor would cut out realy bad..i made a post about this a couple years ago when this happend..put in an inline pump..a/f back to jivin were it should..it worked and that was all i cared about
