It doesn't add that much. I wanna say I remember one of the superchips guys saying that the 93 tune gained 21 hp, but who knows. I like the 87 tune the best. What's more important is the hp it adds through the entire powerband, not just peak hp. If you don't have a superchips, and won't be getting headers, get it or the bullydog
