I'm ready to jump into doing my on tuning, I don't want to make a mistake by purchasing the wrong tool(s). My current vehicles (2005 GTO & 2015 Sierra) are stock with the exception of exhaust/headers, Intake tubes, basic bolt on's. The future may involve a cam swap. If I'm understating correctly I cannot add/log with a wideband without the pro version? I'm sure there are other advanced features in the pro version as well. Any advice would be greatly appreciated.
