Getting cooler here now. Trying to do pulls during warmer part of the day, but tough with work. Looks like hit very close to target on boost, a little over at the beginning of the pull, a little under at the end. Cyl 5 still knocking at different times of the 3 back to back pulls. Power feels similar to V5. Using Shell 93 on this and V5 pulls. Surprised if octane would be low?
