The feels like it does not want to stay running.

i probably shouldn't of tried.

Is this possible to run with 1 bar map sensor.

If you have not replaced the sensor with a 2 bar then you cannot run those MAP linear and offset settings. If you set them back to stock you will be good but you will not have 2 bar so you just burned $100. Long story short you need to replace the MAP with a 2 or 2.5 bar sensor.

would it be any benefit to install the MAP 2 bar sensor. Would the gm part# be 12580698 .

debating on getting turbo for vehicle.

Since it looks like you've already burned the credits on the 2 bar OS I'd say it's well worth the price of the MAP. Thats the part #, yes. Even without the custom OS it would allow you to log boost.
