Ok I'm really thinking about EFI live since the price drop. First question is if the software will work with my MAC apple computer. Next is I'm not really looking for big power, I have no intentions on replacing the stock trans. I'm mainly looking for a mild tune with an actual real life increase in mpg. I run the hypertech and I'm happy with the power increase, dont care for more power(its nice and safe), but I would like more mpg. Also whenever I ask about mpg tunes, people say buy efi live and download this tune. Do I need to buy these mpg tunes or do I just need EFI to install these tunes.
Thanks

Won't work with a Mac OS. :(
