Default Rough running & cutting out

Hadn't started the car for 10+ days and the battery was completely flat. (again!)

Managed to get it started off the vRS after a while, but now the car is running very badly.

It is cutting out when coasting (loss of P/S).

Idle is much lower, even bouncing off 0 RPM & hunting.

Boost is all over the place - at peak, the needle is bouncing, whereas it was steady before. Defi's are buzzing, don't know if overboosting.

Hesitation thru rev range under higher boost.

Have tried both high & low boost settings, with same problems.

Any ideas??

Is the map lost or affected when the battery dies?? (That is my only thought...)

Can you manually adjust the idle?
