PSI Power Box, simple plug n play job from Rimmer Bros and others transforms the beast but will shorten the life of your auto box. Remember to do the 30K oil changes on the box if you fir one.
The throttle peddle has a very long travel in keeping with off road use, you do need to floor it.

Previous owner put the PSI sticker on the back of mine, but not sure if it was removed. How big is it and where abouts would it be located?

It's about the size of a packet of cigarettes with one maybe two wires, you'll normally find it somewhere near the fuel pump mines strapped to the fuel filter...

I put a powerbox on my old disco td5 they are similarly sluggish as the diesel RR. Ups the bhp from a lowly 136ish to a lowly 150+ ish did make pulling out onto motorways slightly less of a pants changing moment. Not as good as a proper ecu remap tho.
