is it possible to put a rally art chip in a tj manga sports and would it make much of a diff and how much would this cost?

You could, but it wouldn't make much difference, and may be harmful since it's expecting a different cam profile and higher compression so the mixtures and timing will be wrong.

To do it you'd need to purchase a complete ECU from mitsu spares or find a wrecked one and nick its ECU.. either way, probably pretty pricy compared to buying a piggy back.

Is it true the tj sedan and sports both have the ralliart engine but the ecu chip on them reduces the power to suit the family car profile? and say u where to get a new ecu performance upgrade how much kw at the wheels u probly will get?

No, that's not true. The Ralliart engine has a number of internal modifications that are missing on the lower spec models.

What is true is that the TJ Executive, Advance, and every other model have the same engine as the 8kW more powerful TJ Sports and VR-X. The reason for this is that the Sports/VR-X have straight through mufflers and the Exec doesn't.

On a stock engine? About 8kW ATW (10-12kW at the engine).

must remember that Magna ECU's are combined engine and transmission. So you could put a 5spd auto Ralliart computer into a 5spd auto Vrx but I dont know why you would. I need a ralliart computer to suit my ralliart engine but being a TH 4spd auto the ralliart 5spd auto computer wont suit

Have you thought about sourcing a 5spd auto box?
