I installed my Predator last week. I installed the 40 hp. and i love the extra power it has. Finally my truck feels like it woke up and is ready for some fun. I could only imagine what this truck could do at a higher tune.

I just put mine on yesterday. Used the 65 hp tune. Love it. DIC seems to read about 3.3 mpg above my hand cal'd milage check. Also motor is a tad louder, but all is O.K........RICK

I also run the 65hp tune. I might try the next up one after I install the Cool Duals and gauges.
