What are you wanting to do (concerning a tune)?
I only ask because I've had a couple of guys do L67 swaps in these cars and found out they could NOT use a W-body L67 tune in the Intrigue due to the VATS issue.
The Intrigue used the PASSLOCK type VATS system which was not used by any L67-equipped car until 2004 model year (Impala SS and Monte SS). Loading an earlier W-body L67 tune into your PCM will result in a no-start condition.
But you can't use a 2004 PCM in your car because the A/C request signal gets communicated to the PCM from the HVAC control panel in a different way (in 2004-05 L67 W-body cars) than it does in your Intrigue. I'm also not sure if there will be other inter-vehicle communications issues between modules if you use "too new" of a PCM.
