Nope, I think that I am having some issues with mine. I did drive a red 06 for the day before buying my black 05. the red 06 didnt handle as well (felt looser), had more miles, more wear, and more expensive, but did have, noticeably, more power and better fuel economy. I just assumed it had k and n filters or something and I only drove this one for 10 minutes so didnt get to test out fuel economy. I just want it to run like it should and get mileage like it should. I didnt buy it just for economy or I would have bought a Prius, but it shouldnt be at V8 truck economy either, lol. Hopefully will get to the bottom of it this weekend??? Any suggestions much appreciated/// Chuck
