I was thinking:

87 Octane Econ
87 Octane Performance <----which I'll normally use
91 or 93 Octane Performance <---which I'll use when towing

Just wondering if I should do the 91 or 93 (ie, can't always find 93) and which choice you guys use around town?

The early-upshift trans bugs the heck outta me, as well as the lack of true WOT until 4k rpms....

Thanks!
