  1. Thanks Tyler, I guess the main reason I went with a 4000 instead of a 3000 was I was more concerned with holding a steady 70 mph speed while towing up the mountain rather then getting everything moving, also lowering my EGT's was another big concern. With the stock, I had really overheated a few times pulling the mountains and the 4000, according to my research, was good for 200 degrees less than the 3000 keeping EGT's below 1400 degrees, which I have still never seen. When I was completely stock I had tractor trailers passing me on a 4% grade and that's when I decided to do some mild upgrades. With my current setup, she still comes off the line well and even the lag with the turbo spooling is barely noticed even with the camper attached. Like I had mention earlier since I took the 75's out and went back with stock, she is still very driveable and tows well but the difference between the injectors is like night and day. I am planning on have my other engine built and in the truck by December, so I'll let everyone know how it comes out.
  2. Really appreciate all the replies; at this stage, turbo replacement is out of the question $$$ unless I go back to my stock turbo. The DDP injectors are brand new out of the box, but I have reinstalled my stock injectors which produce no smoke on tunes 0-3 and then only mildly on 4 and 5 until I come up with a solution. I am currently in the process of rebuilding the original engine as this so called "130k" motor I just installed has excessive blow by. Once I have completed the rebuild I will probably reinstall the 75 hp injectors and I have an AirDog 100 ready to go on the fresh engine. If after my rebuild I still have excessive smoke on the lower tunes I will probably step down to 40 or 50 hp injectors or maybe just stay with the stock ones as the truck runs very strong with them, granted not as strong as with the 75's but, it's something I can live with.
  3. I recently came across this post while looking for a solution to the same problem. I have an 02 2500 which I had done some mild upgrades in an effort to improve towing of my 8000k 5th wheel camper. Those upgrades include Edge Juice w/ attitude, 4" turbo back Banks exhaust and intake horn, Filtration Solutions oil by-pass system and cold air intake. I recently galled #5 piston and cylinder and replaced the engine with a use 130k mile motor from a 02 3500; in the process I also installed a new ATS 4000 turbo and pulse flow exhaust manifold and DDP 75 hp injectors. Needless to say is smokes like the Norfolk Southern is coming down the track, even on the lowest setting of the tuner. I can ease the pedal until the turbo spools and minimize the smoke, but that's just not an option when the camper is attached. The VP44 is a reman that came on the used engine and appears to be stock, so I was wondering if Greenlee found a solution and what it was? Any help would be greatly appreciated...
