SCT Livewire

Just got my Livewire installed

It has 4 tunes installed in it from the dealer
Street
Performance
85hp towing
50hp towing

and trans only

there is a disk that came with it but I can't get it to work on my computer.
I want to run it on the tune that will do the best MPG for now and I don't want to push my luck too far with breaking something.

Does anyone know what is the difference between Street and Performance?

the disk is nothing more than saying this is an sct product thats it. as for the tunes. the canned tunes suck honestly. id go custom but the best fuel mileage believe it or not will prob come from the highest hp setting. that being performace IIRC. i run my race tune and thats where i get my best mpg's. some might disagree but most people i talk to including 2 best friends and dad run on race tune and get the best mpgs there as well. keep your foot out of it and that will help to
