you can't accurately tune the fuel settings without a dyno and a wideband.. what i can tell you is that a google search on "tuning a apexi vafc" leaning the h22 5% across the board netted him very good gains... although this isn't the case for everyone... it's a starting point... get yourself an a/f gauge too
