Chicago HHR SS
Will the tune that you develop be for both the 5spd and Auto?
And how will it affect or how do you project it will affect the outcome between the two?
I know you really have to do both, to get the answer, I guess what I am hoping is with all of the tranny talk with the Auto, that any increases, the Auto will be able to withstand the changes...
Greetings - new to the site.
My HHRSS is only 2 weeks old with +/-1000 miles and I can't quit smiling when I drive. 29 MPG all day long so I don't mind premium fuel.
Has anyone gone down to 89 octane and seen any change in performance or experienced knock?

Would gladly let you have mine, but I am in the Philly area
