91 Octane

3rd gear pull. 93 Oct gas from QT but 91 Oct tune since 93 had big timing corrections.

Here's the first timed runs of the day. first run was very slow but after getting to understand the course, the times got a lot quicker.

First time going autoX and first time taking my 2008 speed3 out to rip. Near the end of the day, we got to do some free runs. Noticed high knock during one run. Turns out the high knock wasn't during the run. Probably caused by the poor road on the parking lot.

trying to find out whats wrong
