No, not that I know of anyway.WhiteWolf wrote:
This might seem the daftest question ever but is there an easy way to disable the turbo through a switch of some kind...
Question is, why would you want to?
It would be painfully slow without a functioning turbo, much worse than the N/A 1.7, due to the much lower compression and the fuel/ignition maps expecting to see boost at increased revs.
Edit:
Ah, is this while you send Robou your boost ECU for modification?
If so, the simple answer is no, as that ECU does boost AND ignition, so it simply wouldn't run.
