91 Octane

Replaced both o2 sensors with NTK and now fuel trims look great.

Shell 91octane. Low throttle highway cruising.

New engine with the settings changed in the system so it hopefully doesn't explode again.

Heard a weird noise when at abt 6k rpm in 4th and felt like it cut power was gunning it. Error code 2A87 (DME: exhaust VANOS, mechanism) gave me limp mode along with error code 3100 (DME boost pressure control, deactivation) but i was already getting 3100 prior to tune. Code 29DC as well, (cylinder injection cutout)

e18 tune on slot 1
