superchips for durango

Anybody hear of this superchips.com?? They can reprogram the computer and get an extra 46 HP and 59 ft/lb of torque. Anybody have one and try it? Did it help your gas mileage any?? How about the K&N intake system, (not just air filter)??

I can see that reprogramming a chip can get ya 59 ft lbs of torque, but getting 46 extra hp is hard to believe for a non turbo/supercharged engine. Unless the engine is way way underrated to begin with? Some people posted some aftermarket chips and maybe a couple from Mopar can get you about 10-20 HP increase which looks more realistic.

Your right. I just went to another site where they sell the superchips and they are quoting only 21 HP and 35ftlb of torque. Can anybody tell the difference and have you seen better gas mileage??
