I had a stage 3 map done by them, all the correct hardware, and health check carried out before! Mapped fine and he left the map too rich and the car was pinking! It blew a piston on the way home, I called to get help and didn't want to know, wasn't even sorry blamed it on the wrong fuel in the car which was high octane which he advised me to put in! It got really ****** all over another forum
