hey guys i been trying to tune this FD on a power FC and it starts and runs but has a high idle around 1500 and its running extremely rich. Its so rich to the point it fouls out the plugs. Thing is I havent even changed the injector duty cycle or anything with the fuel mapping. It has stock injectors and stock turbos.

 

What Mods?

What map is the PFC running?

What is running normally with the stock ECU?

 

It depends on the mods, and if the PFC map is stock or modified.
