Thread: PCM upgrade

I recentley pulled a pcm from an '02 Bonneville and was going to send it in as a core for an Intense or other recommended pcm tune.

However, when I compared it to the on that's in my '01 GT. IT WAS NOT MADE FROM THE SAME MANUFACTURER.

Mine had Delco on it & the other off the Bonni had Delphi.

Is there a difference? Or should I worry about sending it for a core.

Do they use the same pcm that came out of your car for the tune and return it?

Can someone please move this to the pcm tune section? Thanks.

Does anyone know the diff?
