if you are happy, that s already good enough

in that case, if you have stock header, the tune does t need t change much, the first cat is still there blocking everything
when i switched to *Only* catless front pipe (all rest stock) while still NA i barely could rise timing from 5.5 to 6.5-7k rpm.. with supercharger it s similar behaviour
as you said, at least you gain in knock relief
