I think that's pretty much how it makes power.

Ya I guess the more I think about it this may be a stupid guestion since im sure they will be raising the boost.

on all other cars it raised boost and modified timing and AFR, so I think it uses all 3 (and maybe more things? iono) to make POWA!!

That is a good question.

Especially with Calif. 91 octane, it may not be possible for them to increase the boost, lean out the AFR, and advance the timing without having problems with detonation.

Cobb tends to be conservative so I wouldn't expect anything radical.

The Cobb map will modify timing, fuel, injector duty cycle, A/F, boost..etc to make power. It does a lot more than raise the boost.

They specify the octane rating to be used with each map. In the past they have made two versions of each map, one to be used w/91 octane and another for 93.

I can't find the post, but Josh or one of them said as much awhile back on the other forum. A slight increase in boost, but nothing major.
