Got My Gryphon Today

[bigburg]

Just got my Gryphon today and I am lovin it so far. I am running the stock tow tune until my custom tune arrives.
Set up and install was nice and easy. The dash pod fits like a glove and matches my dash pretty good right out of the box.
Downloading the tow tune only took 45 seconds or so. Once it was complete the truck started right on up with no hesitation.
Ok so overall the truck idles a little lower than befor. With the canned tow tune initial throttle response feels unchanged at low speed. But when you give the go peddle a little push the truck comes alive like never befor. Response is more imiadiate and the shift points are much more snappy. On the freeway passing and merging are fun and easy. Downshifts happen right away now and RPM's are held higher for longer.
The user interface is simple and straight forward. Setting everything up was easy and so far all info such as RPM, MPH and fuel usage seem accurate but I will continue to check.
If the custom tunes are as good as everyone says I will be like a kid on x mass day.
One question, what is the second connector for on the wire harness.
