Trying to help a friend out. He's got a 2013 Camero ZL1 supercharged. As if that's not quick enough he's had it mapped and someone's made a mess and doesn't want to clear up the mess. It's running really rich . Also be good to know who has Camero diagnostic kit for mag ride suspension , wheel sensors , engine warning light etc etc. Tried Ian Allen in Virginia Water near Ascot and they don't want to know. Thanks
