Thanks. Compliments about my pictures are always appreciated.

I'm 99% sure the Jimmie ECM would have worked quite well had I plugged it in as it was, without changing the chips. After all, the truck it came from had the same 2.8 GMC engine. I changed them only because of the California smog requirements. I don't think the color, blue vs black, matters.
