You might want to go back to a stock tune and see if problem still exists. If stock tune doesn't improve things, you need to start looking for bad parts, wiring, &c.

Thanks SouthArk. Took your advice and cleaned the MAF sensors. Really easy job as you said. They seemed pretty clean, maybe a very thin sheen of oil on them, probably from my old Gruppe-M intakes.

I cleaned them thoroughly with CRC MAF sensor cleaner. Haven't noticed a difference after a very short drive which I logged with Nissan Datascan 3 again. Will go for a longer drive tomorrow

I'll look into the throttle bodies next. I heard they are easy to damage so I might get a professional to do it

Should mention the slow response also existed on the stock tune
