I had a similar problem one year ago and it was a faulty coilpack.
Might want to check that too...

I doubt its a fuel, or ign cut. If you have a 300zx filter, it shouldn't change too much, but if you have a 300zx maf, you should check out the settings on your safc/emanage/ etc that you're using for tuning. Typically if you have the in and out settings for the maf sensor right, the correct amount a fuel / air adjusted is not always right.

Another thing could be under high boost/load the spark plugs? when did you last change them?
