I'm new to tuning and have been watching a lot of YouTube to learn. I was wondering what is the best portable wideband for the MPVI2? Does the Pro feature have that? Do I need a wideband to tune MAF? I want to be able to tune in Lambda (according to Goat Rope Garage). I plan on tuning for others and I need the wideband to work for a wide range of vehicles. Thanks in advance
