Anybody have idle problems after installing larger injectors?

A friend just put some 31lpm nozzles in his and it dosnt idle right now. Watching the commanded fuel with the efi live scantool i can see the mm3 bouncing between 0.0 and 3.0. We can turn on the AC and with that little bit of load it almost completly smooths out the idle.

The other problem it has is that if you rev it up it will hang at a very choppy 1500-1700 rpm. The chop is reflected in the commanded fuel also.

The truck ran perfect before the larger injectors. Whats the deal?
