Probably added a few degrees of ignition timing OR played with A/F levels OR TqMgt...also 10hp isn't at the wheels. GM still is stupid and needs to offer 1500's with a 2500 driveline.
but i have a feeling the 10 hp jump is more of a marketing mod

well i guess they only way to find out is to dyno a new one and compare it to a dyno from a stock 02 or 03. 10 at the crank should make a few more at the rears right?
