The example given below is a 6.3 litre V8 Jensen FF. It was brought to us all the way from Cheshire after a few other garages had attempted to tune the car however the erratic running, and unreliable start up remained.  So just like we do for any car, we carried out the provisional health checks of all fuelling, carburation and ignition components. 

After finding 4 or 5 collective issues it soon became very clear to us why this car was a little poorly, and what needed to be done 'before' it was ready to be optimised and tuned.

After rectifying the key ignition, fuelling and carburation issues which were making this car run poorly or not run at all.....it was time for it to be tuned and bring back that V8 growl.  The feedback we received afterwards was that the car now ran better than it ever had done in many years of ownership.
