Came across this today when a customer came in for a retune

Car is a 2008 VE COMMODORE SS UTE

[Dieselman]

Is it a HP Tuners COS maybe???

Yep, that's a HPTuners custom OS, not much you can with that one with EFILive but flash a standard OS back in.

thats what i was thinking (HPTuners).
The car has a mafless tune already but i'm doing a head and cam and fast 102mm manifold and body upgrade.
So flash back a stock tune and retune to suit.
