Will a normal diff when floored leave two tyre marks. I did a test today on a road. I floored it and spun the wheels. I came back and checked it out and there was a tyre mark from each wheel. This was in a manual by the way. Does this mean i have a limited slip diff. It wasnt a long mark just about 3m long for each tyre.

Yep, that means you have an LSD

It is most likely LSD, however, single spinners can do this sometimes as well, and LSD diff can sometimes leave only one mark if the clutches slip.

To be 100% sure, jack up both rear wheels at the same time with the car in neutral, and park brake off. Turn one wheel. If the other turns in the same direction, it's LSD, if it spins in the opposite direction, it's a single spinner.

Re: Also

you wont always get two tyre marks, just when theres enough rear wheel kW for both wheels to do some damage

like an LSD will have SOME power to BOTH rear wheels at all times, but if say 80% of it is on the left, then only the left wheel will spin out, so dont use this as an indication

Grass is a good way to test it :)
