Advice on upgrading

Guys I’m looking for advice. I have a land rover Freelander 1 05 plate. It’s the 1.8 petrol version. Despite it drinks like a trooper I’m thinking of doing a complete upgrade of it mods etc.

I’ve been told a remap won’t give it more power or help performance which puts me off.

Is it worth me doing this a project and can the engine be improved at all
