Wondering if it is safe to tune a pure850 and catless downpipewith only jb4. I found what I think is a good deal, locally and would like to take advantage. I will eventually get an unlock/tune, but was wondering if this was safe in the meantime?
New Supra owner here. I recently picked up a used A91-CF in white and I am wondering if there is a registry where I can check what number of the 600 built mine is. Does something like this exist or does anyone know of a way I may get this info?
