(when running 10.5)
I belive that somewhere here on forum (other thread) was mentioned that SXX highest profile is like profile 6 ond SPX. Dynamic timing is on pofile 7 and 8 if I know well. When SPX starts changing timing it's like second gear on car. It's crazy.
Personally I ran SXX only with mod motors so I can't really compare these two. Sphere TC Spec and SPX is HUGE difference - mostly on straights.
