I CURRENTLY HAVE A 2004 CADILLAC CTS-V WITH A K&N COLD AIR INTAKE AND A GRANITELLI MASS AIR FLOW SENSOR. THAT IS THE ONLY MODS THAT I HAVE CURRENTLY DONE TO THE ENGINE. I HAVE RAN 13.1 IN THE QUARTER MILE AND JUST RECENTLY MY WIFE BOUGHT A Superchips Programmer/Flash Tuner FOR $529.00 I AM WONDERING IF THERE IS A BETTER CHIP FOR THIS CAR BEFORE I USE IT. ALSO, DOES ANYONE KNOW WHAT KIND OF POWER INCREASE I SHOULD EXPECT? WHAT WILL IT DO TO MY 1/4 MILE TIME? IS THERE ANY OTHER MODS THAT YOU WOULD SUGGEST?
