I keep switching on the 91 and 93 because the canned tune requires 91 or higher. I wasn't trying to be confusing. :o I wasn't sure if that's the standard high as a lot of areas don't offer 93 octane. That being the case, I wouldn't want to be in a situation were I need 93 and can only get 91. I don't know if it makes a difference or not. I would gladly take a 93 performance tune though. If it produces better numbers, I'm all for it. I'll probalby order a 87 as a back up tune.
If I get two custom tunes. Say a 93 Performance, and an 87 Performance, what canned tune would I keep? Level 1, transmission tune?
