    I'll have to ask them again but I don't see anything in any of those posts that state (from Blackbear themselves) that they offer a tune made exclusively for 93 octane. There would have to be 3 options then- 87-89 octane, 91 + octane (which is one of the tunes they sent me for loading with my Autocal) and a 93 octane. Myself, I don't even have access to 93 octane here. Our Premium grade is 91 or 92 octane, mostly 91 at 95% of the stations. All I saw them state is that 93 octane would yield the best results. I'm running a blower and Whipple states to use 91 minimum and if available use 92-94. Justin told me to use minimum 91. So then @JennaBear please set the record straight- does BB offer a tune exclusively for 93 octane as some members here have stated or only a tune that is for 91+ as I've been led to believe? I don't see why they would offer a tune that works for a grade of fuel that might not be available.

    A tune for 91+ will work better on 93 than 91, but still acceptable on 91 octane. There is no downside to increasing octane compared to what it is tuned for.

    The only time we may dial a tune back is if it is written for boost in Southern California, Arizona or Nevada, as those areas have exceptionally poor quality fuel. Our SS loses over 50hp potential running 91 octane CA gas compared to 92-93 octane.

    Then you're saying your highest-performance tune is 91+ and not specifically a 93 tune correct?

    The 91+Octane tune that we provide for N/A purposes would be ideal on 93 octane but acceptable on 91 octane. Timing differences are insignificant on most GM N/A engines between 91 and 93 octane.

    How much does a retune cost?

    Blackbear tunes are lifetime. Free retunes once you pay the first time.
