Had a similar issue with my RB20DET, turned out to be a dodgy TPS.

What exactly exactly was your issue?

[Missileman]

When the engine was cold it would idle perfectly, but when you moved off and depressed the accelerator peddle it would splutter and cough until the revs got above 2000rpm

As soon as the engine was up to temperature, the issue disappear.

I swapped the TPS with a known working one from a mate, and adjusted it as per engine manual (p367) and the issue totally disappeared.

Did a boost leak test. Found nothing.. Checked all vacuum lines and hoses.

But I logged my sensor readings using NDSI and it seems that I'm hitting a fuel cut on one of the banks.. What would cause that? A misfiring coilpack?

Here is a sample of the readings:
