Hey everyone Im thinking about putting a chip in my car to try and boost my fuel curve, horsepower, and total torque. I have yet to have any luck trying to find such the chip for My 2001 Is 300...... Im also looking to change the ring and pinion to 3.86 I heard that this will give me increased torque... So my question is what are the good chips? will they actually help?? and where can I find them.....HELP WOULD BE GREATLY APPERCIATED
