Trying to gather multiple tuners' experiences dyno street tuning a H22a turbo setup.

What AFR have you seen make the most and safest power for the H22a motor? 12.1, 11.8, etc...

What fuel pressure have you seen the best results at? 40psi, 50psi, etc...

What temp on EGT (cylinder 3 before turbo) making the most power?

Best Vtec point - 5600-5900?

Timing low speed ignition table (18 - 22, etc?) + high speed ignition table (10 - 23 etc?)

Boost by gear or boost by RPM?

12;5+ depending on how the tq curve looks at certain a/f and vtec at 5200 and you can play with it at different point to see where the graph looks smoothest pwm setting depends on you drive on street and see what psi is best for each gear and go by that
