I have a tune for a 04 Impala 3.8 Supercharged that I'm using for my base tune. Can I flash it to any P04 PCM or does it have to be the same part number as the tune. I have a bunch of pcm's from earlier impala, Bonnie's, Montana, and Venture.
I will be putting the pcm in my 01 Venture. The little testing I've done the 02 Monte PCM I have works in the Venture, Basically just need one that does class 2 data for gauges
