I have a 2000 ss m6 just swapped in a 60l lq4 the car runs great , very good oil pressure, but cant hold idle it bounces everywhere.The problem is idle is bad and my predator is saying my mass air sensor is way off. Should i use the ecu from the silverado mapped to the lq4 a4, or to my ls1 m6

please help my predator has the option to switch to a manuel transmission

You don't need a new PCM, you need to have your car tuned

Get your IAC counts into the 45-75 count range at hot idle firstly and then tune from there.
