8.1 only question
I was just wondering if anyone out there has used this ultrapower ECU? It looks to be geared just right for waking up the 8.1 and gains some MPG. https://www.brazelsrv.com/Ultrapower-GM-Workhors...

All I can say is email them after looking at there website. They will send u all the info that you need. At first I was on the fence, but took the plung and had it efi live tuned. Easy process, the 8.1is an absolute beast for sure. My close friend has one, Love that power of the big block. He has not done the efi live tune yet but will when possible. All I can say is I’m a happy customer, I don’t know if there are other tuners out there. I stand with my comment about black bear... in my opinion and experience.
