So, I think I know what I should do, but I want your opinions.

I have a GSR and LS tranny. I don't have a tranny in my car right now cause I'm in the middle of swapping out the clutch. I'm driving from CO to AZ tomorrow and I need to choose a tranny. My dilemma is that I will probably be going to the track in AZ and I run much better and am tuned on the GSR tranny, but the LS tranny will do so much better for gas mileage.

Thoughts?
