Do you have the 5 port or 3 port? I have the 3 port and am still breaking in. It takes forever! I'm starting to wonder if I'm breaking it in right cause I have almost half gallon through it and it's not fast yet. It seems like it's running rich but my temps are at 220-240. Mines bogging on the low end with LOTS of smoke and sometimes doesn't get into 2nd gear or will shift late into the sweeper.
