The Edge Juice is a great choice, especially if you get it as a package deal with the Attitude monitor. The Attitude allows you to switch power levels on the fly, as well as replacing the gauges you see on most modified trucks (excluding trans temp, if you have an automatic). The Edge Juice/Attitude combo keeps an eye on all the important stuff like Exhaust Gas Temps (EGT's), turbo boost, transmission/converter/clutch slippage, engine coolant temp, engine load among others. You set the parameters (max EGT, max boost, etc) you want and if anything gets out of kilter, the Attitude will decrease the amount of fuel going to the engine. This allows you to watch the road, or track, or whatever your driving on instead of having to watch analog guages for trouble and getting your right foot out of the fuel before you hurt something.

Edge also offers a "hot unlock" for the Juice/Attitude that raises the max power output from 100hp - 250 ft.lbs of torque to 160hp and 350 lb-ft. It will cost you another $100.00 for the "hot unlock" code, but be forewarned. Your stock turbo and transmission won't be happy with the "hot".
