Am I the only one here with a tuner lol.. we do not have 93 here and I am not going to mix.. I’m lazy. I can get 91 and 100.. also remember my spark plugs are different And I do not buy gas or drive in a way to get better mileage 😉 But for you @1st K5 .. I will get some logsI've been thinking of trying out Petro Canada ultra 94 but has ethanol and some say they get lower mileage. So, I may try using boostane with shell 91 and try to boost it to 93 octane and see if there's a difference.
The only way we can tell is if we data log.
Get logs with 91 octane and logs with 93+ octane. There we will see if our ecu is pulling timing or not with either or. Maybe @RuffGT can data log 😉
LOL... What plugs are you running? With jb4 set at map 0, would like to see fuel trims using 87 and 91. I'm more curious for performance gains.
Still running the HKS XL 45s... I am also getting it Dyno’d this weekend or next so you can see some real numbers. I will try and get the logs for ya.LOL... What plugs are you running? With jb4 set at map 0, would like to see fuel trims using 87 and 91. I'm more curious for performance gains.
