Like WRC_Fan said, It should run better w/ dataloging. I'd add a 23 head & a set of cams, like crane's 0010's or crower's entry level one's. I'd wonder if a 23 head would make a big difference. Idk a set of cam's do. Since you have the in & out going. Enjoy your wkend.
Introduce Mr. Torsen to the mix
