When we bought our 2012 Grand Cherokee with the V6 Penastar. I saw a Dodge Challenger on the showroom floor with the V6 Penastar. I noticed the information said it has 305 hp where our Jeeps have 290hp. I was wondering if would be possible to try the Challenger ECU setting in a Grand Cherokee? The shift points would probably be way off but, why wouldn't our rigs be able to tuned for 305hp from the factory vs. the 290hp we have now? I didn't compare the torque numbers but, I'm guessing our vehicles are probably programed for more torque at the expense of a few horsepower.
