i just installed the 450cc injectors today to complete the AFC HACK...what a difference...but it's still not running as well i wish it did...i have a JDM H22a...what should my fuel pressure setting be at...also...do i need to retard my timing? or just leave it at the original setting...? it'll boost fine rite till like 5000-5200RPM then it'll just feel like it loses fuel....i have never tried to see what it'll do if i try to keep going past....too scared...somebody help PLEASE!!!!

Same thing here. I am afraid what will happen if i take it to redline. You just need it tuned

update: i turned up the fuel press (it's at 60 psi...is that too much?)...it helped a little...i can take the car past 5k if i'm at partial throttle...but once i floor it...it starts bogging and stuff...i have a CEL 41...so imma try changing out my primary 02 sensor
