Are stock Duramax FCAs "better" than the stock Cummins FCAs?
I believe I heard they are bored out larger or something?
Also, can FCAs from different aftermarket manufacturers be swapped from one pump to another pump without any issues?
I have also found some info that most II pumps use a stock FCA and that swapping in a aftermarket FCA from others (T&C Diesel) can product good results..............no?
