This is even more true on heavily modded cars and FI'ed cars.
I think what your seeing, when the tach is dropping, is just the ECU keeping the car from dropping revs too fast to where it will stall the motor.

Exactly. Most cars do this. Just to prevent the engine from stalling if the revs drop to fast.

Nothing is wrong with your engine...but first of all..congrats on teh VQ35HR. You are one of the first to roll around with that engine in a 350Z.
When you decel, the ECU will fuel cut, and at 1500rpm or so, the fuel kicks back in, which causes that slight pause. No worries...its all good.
