When you log, don’t log pulls from first gear

I believe best practice dictates a pull from ~2500rpm in 3rd gear, going WOT to the top of 3rd gear and if you can, run it up in 4th as far as you can.

1st and second blow by way too quickly for you to get meaningful information. When you shift into 3rd from the top of 2nd, your rpms don’t drop into the 2&3,000s so you have no information there either.

When making a run from 3rd at 2500rpm, take care not to activate the pressure switch at the bottom of the gas pedal’s travel as that will force the transmission into 2ns ruining your run

Looks good mate

Timing being added progressively (bit of timing drop in 3rd but recovering immediately), AFR not running lean, Trim well within limit.
