A mechanic or tuning place should be able to put in the chip easily and it is not illegal to do so but you should advise your insurance company that you have made engine/performance upgrades as if you were to be involved in a bad crash and the insurance comp didnt know about the upgrade and inspected your car they wouldnt cover the claim.
On newer cars after 1999 the ECU is remappable instead of adding a chip and this is qiute hard for anyone to detect and you could get away without telling the insurance company about it.
usually when u get a chip just have a tunner shop put it in casue they wil have to remove the ECU, take the cover off and take the old chip out and soder a new chip
