logged some data, need some input

Here is the log file in excel. Below are also the corrections I made to the ignition and fuel maps. Seems like small increments in the high load, higher RPM area would not make a difference so I made .5-.7 points in change for the AFRs. I'm fairly new to this but getting the hang of it. I just want to know if I am going in the right direction.

Looks much better knock wise but now you are rich as hell. Which is odd with your fuel map. Still too much of a timing jump at 6500+

What mods do you have again? Injectors? Lean spool still on I take it?

Im suprised it's so rich when it was mid 11's on the dynos wideband. I was just on that same dyno last week and its wideband matched mine

I disabled lean spool following the directions in one of these threads.
I think I may be rich as hell in that area due to starting on the factory maps using 100octane Tonoco race fuel.

Wiseco pistons, Eagle crank and Eagle rods
Ferrea 1mm oversize valves using their guides and seals
GSC S2 cams
1000cc injectors
Walbro
Green turbo
Buschur exhaust and many more too much to list

Will smooth that 6500 out.

Here are some more logs.
The very first run, I logged almost no knocks after making changes to the map from the log posted above.(19psi) I can feel that the 3rd gear pull is a lot smoother than it used to be this morning.
I then turned up the boost in the 2nd log to 21psi and logged it twice. Looks good so I turned up the boost to 24psi and logged it twice. It still looks good. I don't get more than 1 count of knock at the knock areas.
Running out of high octane fuel. Got to refuel tomorrow and then tune some more! I just want to know if I am doing this right.

Oh yeah, I switched the fuel map and timing maps back to factory before I started to attempt to tune it myself. It's not the same map that was on the dyno.

Are your injectors scaled well with correct latencies and all that? That can skew a fuel map. How are your fuel trims.

Fuel trims were scaled by my tuner. I didn't touch them as of today yet. They were within 7%. Actually it was -7% for long term which is pretty close and this is at idle. I'll work it out myself but then again, I logged it just now with 92 octane in it and it's within 1%. I guess it's just the fuel I put in. Cruising is about -3% on for the trims with 100octane and spot on for 92 octane.

I'm sure all latencies and the scaling are correct or close.

Well as long as you know your wideband is correct then have at it in the fuel map for your desired AFR. Some injectors just make odd fuel maps I have seen.
