Boosted B16: My xpected AFR?
 

Finally i've boosted my B16a setup and everthing is complete. im running 450cc injectors with VAFC. boost is too low (peak is about 5psi sits stable at 3.5/4psi) my vafc settings are -25 for HiCAMs/Low CAMs. VTEC is set to 4500 RPM. and throttle points are Low=10% HI=90%.

Im on stock inline pump and i've added a small inline pump after the fuel filter. FPR is set at 45psi idle. and raises pressure at about 2:1 when boost comes into play. I have Splitfire Platinum spark plugs gapped at 1mm. ignition timing is pretty much in the middle(dont know the xact timing)

When i paddle it down my car bogs around 4k to 5k rpm and then pulls just oK!! that means its performance is pretty much similar to what it was when the car was NA. there isnt much of wheel spin in rolling of 1st gear.

seems like my car is running rich. but i took 4/5 runs yesterday night and when i took out the plugs today they were golden/rust/copper is color (which shows the fuel is utilized).

Im confused about them :( . because of spark plugs im afraid to lean out more :(.

Based on your information above, you should remove the rising rate fuel pressure regulator. You are running too rich. You should use the VAFC only. Also, reduce your fuel pressure at idle to 42 psi.

FYI...see the FAQ for more information about the VAFC aka VAFC Hack.

There are better fuel management available and are very cheap to setup. You should look into Uberdata or Crome. The softwares are free and you'll get better performance.
