Things to change for Lean Condition
I have a 165 computer, 21 lb accel injectors, SD Vortec heads/intake, ZZ4 cam and I've been working to fix my LTerm-C Counts (which I think is BLM) It's always over 130 and usually ~ 150.
I have experimeted with injector size, gms/mV table, and power enrichment. Anything else? I have lowered my gms/mV table as much as 200, and injector from 22 to 17 and I still see 130-150 BLM.
I am still a newbie so I am not sure if I should just jack these numbers further and expect to find a sweet spot for these numbers or if I am missing something. I notice as I lower the injector number I get hesitation although it's less lean.
Any more tips appreciated!
