Default Anyone have an LS7 on the west coast?

The LS7 requires 93 octane, and in California and neighboring states, premium = 91 octane.

Does anyone out in Cali have a new Z06?
Is it a PITA to put in octane boosters?
Do you put in 100 octane?
What do you do????

If you have a stock LS7, the PCM will detect the knock and back off the timing. Inconvienent, yes. But, still a fabulous car by any means.

I have seen one so far in So Cal.

And I thought that GM would only require 91 like all of their other LS based motors?
I would think that a company as large as GM would have done a better job of research before requiring 93...

There will be one at my neighbor's shop tomorrow (saturday). I hope to get a ride in it . They're supposed to be installing some headers and a few other bolt ons. Can't wait..........

I've seen three different zo6's just this week. I run the same size motor with more compression with 91 cali gas and no problems with knock.
