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?
Maybe you will get a better response if you turn off caps lock? Personally, I skipped your question entirely because it is in caps. I imagine other people find it annoying and difficult to read as well so please... don't do it!
If it's not to late, send the Superchips back and get a dynotune from a good tuner. The Superchips is not worth the money. StealthV tune listed above is excellent. Get rid of the Granatelli MAF sensor, your car is probably running lean and there is no HP increase on the LS6
