  1. Last codes were P0421 & P0431 and 907. first 2 are warm up catalyst efficiency below threshold in bank 1 & 2. Last one is load management operation on vehicle electrical system / DME control module
  2. Hi, as per the title can any one help please? I’ve replaced the CATs and o2 sensors and felt some change but not much. Diagnostic has no new codes. Is it worth remapping for and extra 20 bhp? Thanks
