Engine out missed approach acceleration

[wince]

I wonder if any OPS scholars can point me to the correct information:

I've been told that the missed approach acceleration altitude depends on what is written on the Jepp charts, PANS OPS 3 (1000 feet) or PANS OPS 4 (1500 feet). In my company we always accelerate at 1000 feet regardless.

If this is the case, is this also true for engine out?

Thanks,

W
