91 Octane

Log 1714515676

Have a similar pull with 98 octane - looks very similar so timing corrections are not octane related. Ambient air was ~7C, stock FMIC. Just purchased vehicle, apparently has MC chip tune. Boost is definitely over stock but notice fails to meet boost target by around 3 psi.

V4

The first felt great but the second one, 22_13_22 fell on its face when I clicked 5th at the end, ran codes and got super knocks. I put in a fresh tank of no ethanol 91 just before this.
