Now then, book my car in for a setup at ART due to them be close to me. Just spoke to Tony who is recommended to me and told him wanted the full car engine checking and setting up, cam dialing in etc etc, i asked about if he adjusts the AFR if needed on the fuel accumulator but he says he doesn't touch them as once you go near them they go tits up??

I thought this would be a norm to do or is that right or do tuners norm adjust them ?

Any help people would be cool, thanks alot for your time
