Magnum Force Stage 2 for Trailblazer 4.2L by KC, February 13, 2008

Ease of Use/Installation:
Overall Rating:

This thing was very easy to install. I did it at work on my lunch break (1hr.) and had extra time to drive it after I had it installed. For the money, I don't feel like I've gained enough power. I definitely noticed a difference when the engine is still cool, but once the engine gets hot, the difference in power is pretty much gone, at least from a standstill. On the highway, I notice a little difference all the time. It picks p speed better than it used to when trying to pass or just getting up hills. The jury is still out on the gas mileage, because I am on my first full tank of gas since I installed it 2 weeks ago. But, gauging from where my needle is to where my mileage is, I don't think I am gaining much, if any at all.
