hi everyone, ive done some logs on my engine swap and wanted some thoughts are on the logs. I have tryed editing the logs to 50 lines but every time i edit them i cant save them, any help would be appreciated or what program you use to edit your logs.

The logs look good, but the logged parameters don't tell much.
Next time you take a log please use this preset for cruise logging and MAF calibration logs: https://www.dropbox.com/s/bsfurni0v47lp ... vtpre?dl=0
...and this one for performance monitoring (WOT or high PT logs): https://www.dropbox.com/s/hmw8hc97atbqp ... vtpre?dl=0

You can save these files, go to Dashboard -> Presets -> and import these files.

You really need to use your judgement on this one. Usually when you take a log you are trying to log something relevant (a defect, a behaviour, a happening, and so on), so no way you post a log more than like 100 lines.
A WOT log is usually 30-40-50, let's say 100 lines long depending on the gear you take it in. A MAF cal log is usually a bit longer but the whole thing is relevant for those who work on your tune, so there's no need to throw a very long log on the forum and ask "do you think this log looks good?" without any clue about what to look at in such a long log.

It's like you go to the kindergarten as a doctor and one teacher shows you 150 kids and asks you "what do you think, do they look good?" thinking only about some random kid who pooped himself in the morning and that you don't even see. Bringing that specific kid in front of you and telling you about the symptoms he had is a different story though. So that's how long logs versus short logs work.

I understand, to me the car feels like it's running great With the tune I have on. I just wanted to see if anything should be tweaked or looks ok as to me being new to tuning.

So from the logs you uploaded it looks fine. But without other parameters It's hard to tell why the boost ramps up relatively slow, or the AFRs oscillate as well as the boost, why the ECU requested for AFRs below 10 at 6000+rpm, and so on, without looking at the other parameters and at the tune.

So when you can please take a new set of logs, two 3rd gear WOT logs from 3000 to 6000-6200rpm will do, don't push the engine hard in 4th just yet.

I took a new set of logs I didn't not see the last post before i did my logs. I can get a another 3rd gear pull. i just like that i have zero knock as of right now but I do not want to run to lean. But as far as I can see my fuel looks fine, soon need to upgrade hpfp internals.

Yep, all looks good, my preset didn't log the APP assuming that you go WOT from the very beginning, maybe you do, and if you do go WOT from around 3k RPM then the boost ramp-up is a bit slow - which is ok as long as you like it. From the log it looks like you go WOT around 3500, which is a good practice otherwise.
You should post the tune as well.

P.S.: all 3 logs contain a 3rd gear log actually, I was curious to see the 4th gear log.

I went wot from around 2500 to 3000 rpm in each gear. Hit the button floored it let let off and hit the button. Now to ramp the boost up faster do I need to adjust the BCS extended table. Do I need to lower the % in the lower Rpms?

I'd like to see the tune before giving more advice - that of course if it's not the intellectual property of a reputable e-tuner. The slower boost/torque ramp-up is desired in this case, also considering that you just replaced your engine.
