Apparently in your opinion this is a worth while up grade!
I have seen on here how many more tables you have the ability to tune with this PCM. It makes since that it would be a better engine control not sure I even have a good handle on the 7747 yet. But there again I never thought I would even close to where I am now with the 7747 so maybe I can learn the 7427 too.
What was the 7427 PCM originally used in?
