Tomorrow I will receive an unlocked Cortex 2950 I bought from another G8 GT guy in Ohio. I'm a complete noob when it comes to tuning. I don't track my car (although one of these days I might get in a few runs just to see what it can do) and it is normally my daily driver. I'd like to get its best performance out of it without doing anything too crazy. Its only mods are a Spectre CAI (identical to a K&N Typhoon), a ported TB, Solo hi-flow cats, and a Solo axleback. I normally run 87 octane but would pop for 89 if the tune for that is thought to be beneficial. SO... what are the most popular different tune choices available with a 2950 that most people with similar cars choose???
