Ok, so I've been having this fuel cut issue mentioned here:
http://www.turbo-mopar.com/forums/showthread.php?60617-Still-an-issue-with-a-fuel-cut...I-feel-like-I-m-close-to-solving-it...

I reset the battery and put in a new power board thinking maybe I had a leaky cap or bad resistor....the car pulled nice and hard all the way to redline before the adaptives had a chance to adapt. One the computer "learned", the fuel cut came back...still 4 grand. Does this sound like a bad logic board? Perhaps there's a sensor mucking up somewhere? Different chips in the same SMEC had no effect, although the problem seems intermittent. I can go a week without fuel cut and then it comes back.

I've pretty much ruled out anything mechanical since the problem disappears when the battery is disconnected.

reset the battery again and see what it does.

I did...no cutout again until computer learns.

I don't know how or why I posted in this forum...mods, could you move it to the main "Electrical and Fuel System" forum?

Is this the cal I did for you? I can check and see if it's in the cal. It sounds like it is...

No its one I did with the V17. I run the same tune just scaled to my 40s instead of his 20s and have no issue.
