The 3800SC engines until 2003 used a MAF sensor that was integral with the throttle body. On later DBW engines (IIRC 06-07) the MAF sensor used was a separate inline unit. I am involved in a swap now where I need to determine if the MAF curves on the integral and inline MAF sensors are 1. Similar, 2. Exactly the same 3. Completely different. The engine will use the 03 GTP PCM. Has anyone compared the MAF curves? Result?
