Gas Question....

andrewkd16

Ok guys I have a Nismo 370z and I use nothing but 93 octane like it is recommending. However, I ran by a Sunoco here in Peachtree City, GA and ran across Sunoco 260 GT100 gas. To my understanding its 100 octane and i guess its a race gas...I do have an Osiris UpRev tune but to my knowledge with my current full bolton mods it was done with 93 octane in tank. If i use this gas will i need a tune for it to see power or will i see power regardless? Im not up on my gas knowledge so can someone help.

Last question is if I tune my car for a certian race gas can i still use 93 octane or will my car run like crap then?

Any help will be helpful thanks!
