Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Best place to buy a Superchip??

After more research, I noticed that a lot of people loss HP and TQ with a chip. However, they ran better quarter mile times. I did notice that the Superchips dyno lost less power compared to the Diablo. Also I read that the loss is from an aftermarket Y-pipe? Is this true? Now I am starting to debate wether or not to get a chip. Anyone??
