Replacement GM MAFs are the same part number for both cars.

Re: LS1 MAF on LT1 Engine

Check the P/Ns, if it's the same P/N then they are interchangable. If they are different don't use them; most likely the flow curve (Airflow Vs frequency); which is what your PCM sees to read the airflow is different.

The only way to make it work would be to have the correct flow curve/table and modify/adapt the curve for the LT1 PCM, and have the correct pigtail.
