i have a mild build LS/VTEC and im running a chipped out p28 by Kenji. Now i plan on gettin a vafc before i even start the motor. i searched and theres really nothing that goes into this all that much, but how would i do a street tune with my setup. ie advance ignition timing and play wit af ratio on the vafc i just need a lil help so i can get it tuned ina lil bit so my whoel build isnt a waste of money

 

well don't waste your money on a vafc...buy a wideband o2 instead.
I sure as hell hope you have a wideband o2 before messing with your fuel.
