I haven't tuned the new ProEFI. The old ProEFI turned into what is now the AEM EMS. Last I checked it cost a small fortune to get the hardware/software to be able to tune the ProEFI and John Reed the god of Supra tuning was has all kinds of problems with the system. Things may have changed a lot in the last year or so, maybe they have end user tuning software for it now and maybe it works as advertised now. I don't think I have had anyone ask about the ProEFI for a year or so though.
