Tricky as there is not much space left around the pcb to allow for vents.
I understand, maybe I should try it myself as I have a spare vent somewhere.
On a different note, what restrictions are there wrt the upper limit of MAF readings affecting things like torque and power graphs? Is anything else affected?
Do we know what the max MAF reading is via VAG-COM for the MkV GTI (esp. ED30)?
I know on my RS4 it was 364.08 g/s - mine went flatline at this value after 6300 rpms.
