Timing and fuel mix

I recently discovered that in Sport Chrono and only in Sport Chrono mode my car runs rich and the timing is retarded. Any ideas on what may be the issue. ?

I noticed that after I installed my plx gauge, as soon as you hit sport at idle the the timing goes from + 5 to -7, gets slightly rich, hmm

Without seeing actual datalogs it is hard to say but SC will increase boost along with a richer fuel mixture. Some tunes run on more timing, less boost, others it's vise-versa.
