What exactly does the starwheel do for performance ? And which will make more power, sliding the afc forward or turning the starwheel forward ? or both ?

 

Adjust both your star wheel and AFC.Move the AFC full forward toward the front of the truck and turn your star wheel also toward the front.The star screw adjusts the tension on the spring.Less tension and the governor will push the foot easier at lower boost.

 

the star wheel only adjusts fuel inrelation to boost.. adjusting it too far will cause the injectors to dump too much fuel before the turbo can realy light which can hurt performance

 

Ok thanks cause i took the afc arm out and it runs great if i drive it right, but smokes a little too much ? So if i put the arm back in and adjust the starwheel? if im running a bigger turbo where should i turn it too ?
