Ok, let me tell you my situation.. I bought a 99 dodge 3500 CTD with a auto.and i use it for work, it has dump bed on the back of it.. truck total wieght is 8600#..I know that sounds like a lot, but listen to this.... When i first bought the truck, the thing would only go 63 mph, topped out,, wouldnt go any faster, and the other thing i noticed is that it will only rev to about 2600 rpm, and then it wont pull anymore.. just quits making power. well, after a couple months of getting sick and tired of no power, I bought a EDGE EZ.. I could definatley tell a difference, it then topped out at about 85 mph.. which was a big difference,, but still, it didnt want to make any power after 2600-2700 rpms. i ran the edge ez for a couple months and then my tranny went out.. so i investigated some trannys and went to wisconsin to get a full DTT tranny installed.., tranny works great, but the truck is a dog for having a edge ez, even the mechanics there said a stock cummins will walk this thing!!! I then had a EDGE PULSE put in to replace the EZ which is 90hp. well, that woke it up alittle more,, now i could hit 93 topped out,, improving, but still, no power whatsoever after 2700 rpms... it would just stop pulling.. So like myself, i said,, ok, time for more power... so i installed some DD2 injectors.. Ok, so it woke it up even more,,, no able to reach 101 topped out, but this thing just wont make any power still after 2800 rpms.... So this is my deal and i hope on of you knowledable guys on here can help me out.. i know have the EDGE PULSE, Pump wire IS installed, DD2 injectors DDT tranny, BHAF, and thats it.. I did a 0-60 mph run today and did consistant 10.5's.. i think something is really wrong here...like i said, no power after 2800rpms, and the DTT is set up to shift at 3100, so i actually have to let up on the pedal to get it to shift.. Its just not right.. thanks alot guys.. oh, and here is some info.. fuel filter was just changed. lift pump seems ok....
