Yeah I'm thinking its the tune where the GTO may be stronger stock. I have a feeling I won't gain as much. However, I do remember reading a few GTO owners gaining over 20rwhp with the Vararam and tune, so we'll see. Shows how little I know about the G8, I didn't know it had the LS3 heads. Those with matching intake are on my to do list.
