Ive got an 04 flex 5.3 with a BTR NSR cam with LS1 intake.
tried multiple things and cant seem to get any better.
No I do not have wideband.
Any pointers will be greatly appreciated

The tune shows the MAF is failed but the log doesn't.
Are you running a MAF?
Basically air is fuel. So if you tell it less air is coming in, it will give out less fuel. Pull like 3-5% from the MAF/VE, reset the fuel trims and see what the trims do as a test. You really need a wideband with this setup.
Verify you aren't going too high on fuel pressure and that injector data is right if you changed those.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Yeah I?m running a MAF. I?m guessing whoever originally did tune must of failed it. I have no clue I?ve never messed with any of that but I think I found what?s changed in the engine Diagnostics? It?s the primary ve I?d need to take fuel out right? Wouldn?t it be -.03 to -.05 for 3 to 5%
You'd multiply the table by .95 if you wanted to take 5% away from the whole table.
With how the tune is set currently, yes it's running off just the VE because the MAF is failed.
