Hey all, new face here. I have a question that I hope will help with my decision making.

I have a 2004 2500HD with the big block 8.1 liter, and was wondering: what is the better ignition chip to go with? I have ben thinking of either Superchips or Hypertech. Any opinions on this? I already have a K&N high performance intake kit, and a Flowmaster exhaust. It also have a 4" lift with 35's on it. Right now, I am getting about 12 miles to the gallon...gotta love the big block!!!! Thanks for the help.

If your getting 12 miles to the gallon you should be happy. I get that with no lift and stock tire size on my 1999 6.0 V8.
