How does my Log look?

different turbos can run different pressures than others on the same fuel.
when i said 22 psi, that does not apply to all turbos, just stock
i would say turn the boost down to 22 psi, then see what kind of timing you can get. 1* at peak torque and 5* at redline is still super low timing

Do remember this is on a evo 9, From what i knwo 9's dont take too much timing anyways. What timing should i be shooting for 22-25psi tapering to 22.

Ok sounds good, I will aim for that next time. Also would it be safer to make power by having:
less boost lets say 22 psi taper to 20psi and more timing
or
full boost like 25psi taper to 22psi and less timing?
All responses are appreciated, Thank you

Going richer than 11.0 AFR is dumb, and will not allow you to run more boost and timing

My point is that you have to go down from 12 to 11.
I wont play >11 on AFR without EGT.
Just my opinion...

i wouldnt go above 11 even with EGT as im not tuning race cars, and dont need every last bit of hp.
if my customer thinks they can get more power by turning up the AFR's to 12's, then they can go somewhere else, because im not going to be the person who blows their engine.

SO did some more logging and tuning this weekend... Car feels better but above 6k rps still refuses to take more then 6* of timing.. so My peak timing at 7500 RPM is 6 Degrees. and i still get 1-2 counts of knocks here and there.
Is running 6* ok or does something seem wrong with my engine?

1 count of knock shouldnt kill your motor, I think you're putting to much thought into that aspect. It may not even be real knock.
Post a snap shot of your timing and fuel maps.
