2015 Chevy Tahoe 5.3l with long tube headers (tune help)

[Gadgetsystem]

I have a 2015 Chevy Tahoe I recently installed speed engineering long tube headers and I need someone to point me in the right direction for a tune using hptuners. I know someone will say black bear performance but I’m kinda looking for a cheaper option. I already have hp tuners mpvi3 and I already played around with it but I’m looking for someone who can actually tune it to use the headers to their actual potential as I only turned off Dod and played around with some of the transmission setting.

can you screen capture the fuel maps.

did you data log any "driving" for we can see what the AFRs during your "driving"?
