5000rpm @ 1.4 load will still be 5000rpm @ 1.4 load. The difference is that your wheels will be going a different speed.

I disagree. As correctly stated, the engine is more prone to knock the more physical load there is put on the engine. Physical load, as opposed to "engine load" (which is amount of air ingested per revolution).
After I switched to Ecutek, I made a custom table that adds/removes timing depending on gear. I was able to run a bit more timing overall and a fair bit more in total in 3rd gear. This is what it looks like:
By changing the final drive, all gears are made shorter and will physically put less load on the engine. If I was to change my final drive I would definitely revisit this table. Or if I was still using RomRaider I would look at Base Timing B and see if I could push it a bit higher.
