93 Octane

Highway run

Misfiring

Knocking on 93 Esso. 16C ambient

first pulls after cylinder head repair was completed.

Car threw a code at 3500-4500 rpms

Slight hesitation under partial throttle, notice it most when trying to maintain speed on the highway also it misfires above 6k rpm or anytime the tires spin. The flame map also only works when I’m around 3k rpm driving, I can’t get it to work at a standstill/free reving, don’t know if this is normal
