I just got my truck back from having my VP44 installed. Man, I'm throwing out some black smoke on take off! I might have had half as much with the other VP. I have to mention that I'm at an elevation of 7,000 ft. Even while I'm driving in the traffic at 5k elev. I'm getting smoke. I'm not punching it out on take-off either. Is this something that I should be concerned about? Or should I take it back to them? All my filters are clean. Thanks Steve
