Fuel is close enough to not be an issue.
You have 2 error codes 33 and 42 that should be cleared, then rechecked.
Spark advance at idle is only 10 to 12 degrees and with that low a MAP it could be much better with more advance.
The bog your experiencing is usually fixed with added AE Acceleration Enrichment.

Hey Mark...vortec heads... Maybe it would be advantageouse to start over using BNKM?
Sure would be better spark table... but we have no idea what is used now? Idle spark is way to low... rest not bad...

so do you think i should try more base timing as a start. it is currently at 2 degrees advanced.
could you explain what AE does?
No more base timing because if it is not accounted for in chip you can be over!
AE adds fuel when throttle blades open, like a carb has an accelerator pump. More fuel compensates for more air until stable.
Bring it to my house and I'll fix it!
