I think that you aren't going to get alot of answers because there simply are not alot of simple upgrades that produce real horsepower.

This vehicle is not about going fast. Its about going slow, really, really slow. I agree that it could do better on the highway and the 2007 is getting more displacement to add HP & torque.

But, once you get the H3 into its real element, off road, you'll see that it is absolutely perfect.

Sorry that this doesn't help more.
