Hunting on idle? Which tune guys?

[RockyIII]

Hi guys, my rocket was heavily, visualy modified, probably without any ecu tuning. It has a totally freeflowing exhaust. I suspect the ecu has never been re-mapped and probably on the original map 20050 I suspect.
I have an original air filter, (just replaced) and I'm waiting for the cable for tuneecu operation.
What kind of tune should I do? 20226 OEM maybe?

Assume exhaust pipe picks. Uploaded some to my photos just now.
I'll be interested to see which map is currently installed when the cable arrives. I noticed a custom tune on tuneecu 20050finaldyno or something, 157/145. It might just be the ticket.
Anyone out there using this tune? Interested to hear your thoughts.
