theoretical 91 octane tune for 2008 N/A Grand Prix

[SgtMarshal]

I'm going to go look at a 2008 Grand Prix, non-supercharged either tomorrow or Friday. if I end up getting it, I would like to do some tuning on it. On Overkill's website, he says gains of 10 hp can be had if 91 octane fuel is used. I was wondering if that is because there is less kr and more timing advance can be used. Is there much of the 97-03 tune that is similar on the 04+ cars?

You can't tune 2008 cars. It's a year only computer.


Even on overkills website it says 1997-2007 model year tuning.

I see that, I didn't realize that until after I posted this. I assumed hp tuner would support it, but apparently not as it is a 1 year only type deal and is can/bus
