WORTHLESS PIECE OF SH*T EGR SYSTEMS!!!! GRRRRRRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!!!!!!!!!!! I had my F450 and trailer loaded in town yesterday, stopped at a red light, noticed the 2 speed cooling fan system was running longer than it should, and I was in town, flat level ground, then the light turns green and I give it some juice, NOTHING!! It just chokes and sputters and coughs, I look at my right side mirror and I see plumes of black smoke, I take my foot off the pedal and let it clear and try again, all it does is lurch forward and choke. Now I got 15 people behind me honking and swearing to get going and the light has just turned yellow. Damn it!! So I gave the pedal 1 last effort and off it took, completely smoked the yuppy beside me. I made 3 trips to the next town, and I burned through a 3/4 of a tank of fuel with 35 minutes of highway driving in between trips, loaded. This is not acceptable for an "Emissions Controls Device" to get stuck, cycle and choke the engine and guzzle more fuel, all the while raising my EGT's to 900F while towing, I hit a cross wind and it jumps to 950F, yikes, and it's not even Summer yet. So Tuesday it goes to my BD Performance shop, the EGR delete and custom side stack exhaust goes on, the hell with this god damned emissions bullsh*t.
