As far as performance modules go, I think the Edge is the best one for your rig. For better fuel economy and such, you might want to check out the FASS system at
www.dieselpp.com. The Edge may give you better fuel economy as well. When you purchase the Edge, it will instruct you as to where to put the probe for your EGT's as well as the safe levels to stay at. It will also de-fuel if you start getting too hot.
Hope that helps,
