Hi everyone,
First time posting here.
I have a 2012 Hsv with an LS3 and e38 that had a tune on it, only minor fuel and spark adjustments as the motor is standard.
After a recent trip to the dealer for a service some bright spark there decided to update the software in my ecu.
I want to reload my tune to the vehicle but the OS i have read is different to my original. Is there anything I can do here other than buy more credits and tune again?
