if it's at zero the car shouldn't run........

but yes absolutely if you aren't getting the requested/required fuel at those RPMs you can have catostrophic issues.

think there is something that wasn't relayed to us.

So he "tunes it", then tells you the pump has taken a dump??
Time for a new tuner.....
