Here is my tune. thank you

VE tables are all 0's. Has to be populated now that you've done the 2 bar OS. It starts out blank...

Also the MAP sensor settings have been changed to a 2 bar sensor. If you didn't change the sensor then those need to be changed back. Airflow-->general. MAF sensor linear, original value was 128.13 kpa. Offset was -0.31 kpa. Make sure you're in kpa.

Attached is one you can try as a starting point. Airflow-->general, "Normal IMCR Closed" and "Normal IMRC Open". Paste the table in the attached Excel file into both, change the MAP sensor back to the stock values (unless you physically changed the sensor) and see if it'll start.

Thank you for your help! I did what you said and it fired right up. I feel kinda dumb now though this was a take out package out of a wrecked
2015 chevy SS with 9 miles on it from a salvage yard so I assumed it had all the stock settings in it. I turned the vats off and the emissions codes and changed the fuel pump settings. Were the VE tables from a stock SS? The only things done to this engine is mid length headers and an air intake. Its in a 73 RS Z28 Camaro I'll post some pics in the next day or so.
Thanks Again

You should post the tune and a log of what you have now.

The tune Tom355 posted was incomplete.

He should start his own thread instead of bumping a nearly 10 year old one.

That too, but kudos for using the search function, I guess.
