How will 36 lb injectors run on a stock tuned computer.. I know not the greatest, but will it be better that the stockers in an FI situation?

Way rich. I have 36 lb in a LS6 and I had to set them at 136% to get the AFR back in line. Your stock computer is at 100% it will run them 36%, too rich.

Need to tune the pulse, I switched from 28.8 to SVO 30's (34.54@ 4 BAR). On stock tune it started, ran erratic, but once in gear they were awful.
Tune immediately after swap.

it will smoke bad and idle funny, you need a tune for pretty much any injector swap unless it is stock.

In addition to running badly, you will run the risk of wiping out the cylinder walls due to a too rich condition. Then you're talking about a tear down, re-hone, rebuild.

I was always warned against swapping injectors without tuning it. Always tune the car prior to starting it with larger injectors.
