Best fuel map/ fuel grade to tune for
I have a stock 2009 hhr 2lt 2.4L. It pulls hard but looking for a more power oriented tune. I'm wondering which is the best fuel grade for the power e85 or 93 looking to keep it on basic pump gas but the higher octane pump gas.

if I'm not mistaken you need to have a flex fuel car or be tuned for e85..very important. if your not the flex fuel will not be the best fuel for your car at all. There is a fuel additive called torqo it is the best on the market. you can run easily 94-105 octane. check it out, do a little research.
