Not enough channels in your log. Add these and take another 5-10 minute log.

The tune is start over from scratch level garbage, so I did not even look at the logs.

Wheres the original tune? It looks like someone took a truck tune and copied tables from a vette or a camaro file in places. That tune is awful. Start over and put the right injector data in FIRST. Tune the Air model then idle.

Were you adjusting the VE without the MAF properly disabled? There is a pending P0102 code, so there is something going on with the MAF. However none of the steps were taken to ensure it was forced into SD mode. You also need to copy the corresponding rows of the primary VE into the Secondary VE after making changes to the primary on this OS, it defaults to secondary VE with a failed MAF. If you are running fixed 58psi fuel pressure your injector data is wrong, it is setup for a vac referenced pressure regulator. As stated above, try again, get your injector data setup right first before making any changes.

Hope you didnt pay too much for that.
Here is the tune with correct inj data atleast.
Lots of questionable things in that tune and the datalog shows the MAP senor giving some crazy readings or you have some serious misfires from Spark or Fuel missing and Fuel trims begging for help.
And do you have a wideband?

yes i have a wideband, but i recently just went true dual so its only reading 1 bank. when my maf sensor is plugged in it reads lean asf like 20, but when its unplugged it reads closer to normal like 14 until i get on the throttle then it goes lean again

one of the logs is with the maf unplugged and one is with it plugged in. ig the secondary table is closer to being right. ND also i didnt tune it "the scammer" did

I hope you did not take my post the wrong way. It is just useless to look at current logs when the tune they are from needs to be completely redone. And over 20 years ago I started learning to tune for myself because of a garbage tune that I paid for. The situation has only gotten worse over the years with people selling crap to people who don't yet know any better. Live and learn.

my buddy paid for a tune recently. The guy came to his place and uploaded a tune, started it idled it, revved it up and then said he was done and left. NO driving, no warming it up to op temp, just idled and rev'd.. id be so ashamed of doing anything like that

Oh thats common around here. Their idea of "Tooning" is just to get it to idle.

In the transient section you need to reduce or zero out the min fuel milligrams and PW since you have larger injectors. I made a post about this a while back. But yeah this tune is so bad that you should start over.. else some dumb change that didn't need to be made could haunt you later.
