Hi, K&N sent me the dyno of the intake for 10 Hp and 11 tor. I don't have proof on the Jet tune (15-30 Hp). Now the truck is confortable passing and going uphills. Before the tune, it would sudently jump up in rpms and make the engine screem. It does not do that anymore due to the extra power. It does feel quicker of the line with both mods.
