alright guys I have an 03 Durango with the gutless 4.7, im looking around for performance parts which seem rare. are their any bullydog programmer chips that will actually boost my horsepower or torque? please help if you know something I do not.
thanks, I know these engines aren't much, and I have heard horror stories, but I would like too get a little more power out of it. cant seem too find parts anywhere. yeah dual exhaust and headers, but that's it.
