If you were to tune it ,, i would first think of
whats the
service history the car .(This must be taken into consideration)
And the services you intend to do after a remap/chipping.
Also depending on the answers you find for the above, you will have to think about the gains you are expecting from the 193k engine.
If your can came into my
garage for tuning , i would ask you the same questions and then make a decision with you on the increases your car can have.
Personally i would suggest you ONLY had a mild tune to increase driveability and NOT for massive power.
