This was in the chevy Hi Performance mag. I thought what the heck and gave them a try. Keep in mind that I did not dyno my truck. But I can tell you there was noticable gains. Throttle response was more crisp and it seemed to pull a little more in the 3-4.5k range. I think they live up to what the claim. (or atleast damn close) This was an 04 silverado.
