Pulled out my old tactrix cable and upgraded to the most up to date ZA1JAB01C OEM software thats available for the 2013s. I believe this is specificed in the DI seal fix TSB and thus still Street class legal...
At first the throttle felt quite numb, but its feeling better now and its good to know I'm safer from some of the early tune issues.
Should be ordering Hankook RS4s this week... Ready for some real grip!
