Bocanegra/Ibiza Cupra Misfire

Hello
I have had a misfire on my car which only occurs under heavy acceleration or up hills etc - basically when I give it some.
So far:
New Spark plugs (torque to spec)
New Coil Packs
New Injectors
Checked all wiring to these parts too.
New ecu
Compression all good and the same on all 4 cyclinders
Idles perfect
No oil consumption at all
Now I am stuck. I know its most definitely something stupid just wondering if anyone might have an idea?
