First nice run. It's hard to make a good rec on a 1/4 run but I would remove fuel in your 70-100 column from 4000-6000

If you are going for all out power I'd suggest taking out a couple of degrees, lean it out to 11.2 or 11.3 and add back in timing if you can. You seem to be swinging the AFRs a lot and leaning it out will also give your injectors a bit more headroom. A good hour on the dyno should give you good gains and a smoother plot.

Looks like you're way rich in a few spots. <10:1 is too rich for sure. It seems like those 9.X:1 moments are briefly after spoolup, so that may actually be caused by too much fuel in the 20-60 columns. You seem to hold a steady 10.5-11 AFR in your high load columns. Might be a good idea to drive around a bit in 40-75% throttle and log to see how you are in your middle load columns.

You can still probably lean out a bit overall, but that isn't as glaring as those 9.X spots.

It also looks like your timing is slightly higher than most run around 4500-5500 rpm in your 70+ load columns. But you're not knocking, I'd just keep an eye on it.

You can probably get rid of that knock by putting in timing numbers in your 0% column from 4750 RPM and up. It will kill any timing transition while drag racing since you should stay above 4750 when drag racing. I run something like 26 to 30 degrees from 4750 to 7000 RPM in my 0% column. I think the car drives hard better this way, at least on the strip.

Driving wise, you really short shifted into 5th gear. Looks like you shifted at 6000 rpm and landed in 5th at only ~4300 rpm. Run 4th gear out a bit more. 5th gear is an overdrive gear and a huge gap from 4th.
