I had somebody want this tune for me to download and he ordered it from a tuner. I'm confused but the two tunes i'm confused about is 100hp and 400hp. Ok the 100hp is at the wheels that's how the tuner rates his power levels But 400hp which isn't at the wheels so what would a 400hp tune be at the wheels? more than 100hp? Oh it's a 2003 LB7
