So it seems some vote for a mild tune and others warn agains it. I was looking at the Edge Evolution (15001) mainly because I can use a mild tune, adjust shift points, and monitor EGT. My truck already has a trans temp gauge in the dash. Does anyone find them to be less than acceptably accurate?
The factory dash mounted trans temp gauge is actually a 3 position idiot light, Cold, Operating Range and Hot. You will be much better off getting a real way to read the real trans temp with either a stand alone gauge or reading it through the OBDII port into a phone or tablet and a monitoring app.
I would also recommend visiting and joining the best Excursion online community on the web over at http://www.ford-trucks.com/forums/forum29/ There you will find lots of EX fans with tons of info and help to make the big wagon even better.
