The mods for this single turbo do not show any porting and that is confirmed by comparing the timing to stock timing. More advance in some places.

Fuel is leaner than the stock set also. Maybe due to internal coding changes for the 1200 secondaries.

 

"Internal Coding Changes"?

 

Since XS programmed the PFC, they might have changed internal parameters that can not be done with the commander.

 

nice thanks for doing the work. Interesting, but as you said if the base is changed, who knows?
