So, what do you think happened to my car? It was white smoke. Not blue. And it was puttering. It happened when I got on it for a few seconds and let off. But it stayed that way until I re flashed the tune in my garage. I remember not adding fresh fuel until after I flashed it. And the white smoke and puttering stopped after a reflash. So probably something in the tune went bad? Maybe the tune had an injector stuck open and reflashing it got the injector to work? No noise from the engine. Running super strong. Im baffled. But happy.
