Ok here I go. I have a PDR HX40 with DDIII Power Max 3 with remote and Edge EZ. When I got it all together it ran like a mad truck but one day I was into it and it made a sound like a pop noise but a very little pop noise and then the truck slowed down. When I put everything on it I used to just floor it from a stop and it would take off and spin the tires but now after that pop noise I floor it and this thing sets back and smokes and does not want to really take off as fast. I have 38 psi of boost and 15 psi of fuel and 10 with lift pump on at WOT. I checked for leaks from the boost side of it and can’t see anything. I can feel the change in performance when I adjust the Power Max up and down. The trans shifts fine and it does not change if I put it in manual range. How can you tell if you have a concern with the Edge EZ? . I have a friend with a comp box and 275 injectors and an hx 35 and he just leaves me behind now what gives????????

you may have blown the headgasket--either across cylinders or you're pressurizing the coolant system--watch your water temp guage when you get on it and see what happens and report back----
take the boxes off one by one and do some test runs(before and after removal) and see what happens --report back---chris

Re: temps
I would check for Boost Leaks again. What happins is the rubber hoses will pull back underneeth the hose clamp, once you see one that opened up you will know what I am talking about. The hose don't really "blow off" but just part of it will streatch, and pull out from under the clamp. Probably in the place thats hardest to see.

no air bubbles in the water ??? [as Chris was saying ]. .
and the blown boots is right in there. . maybe a hole in one of the buldge connectors as they seam to be weak with higher boost... what boost did you see at the highest ##'s. . air horne tight ? look at your intercooler for a blow out [pressure test the entire system from turbo to air horne. [PVC caps in the rubber connector one with schrader valve and pressure gauge to pressure test. . cap at each end of the system]

boost??
Well I just went threw the hole system and found no leaks, I even went as far as removing the air cooler and cleaning it out and pressure testing it on the bench. I checked all hoses and intake gasket still nothing. I am going to change the intake gaskets and map sensor. I did find out that the ED EZ and Power Max 3 is working with some test removing and driving. I am down to it has to be the map to pcm? Turbo, or in the head and valves???? The one thing I have noticed is that I have no turbo bark and when I shut the motor off I don’t hear the turbo spin down like I used to. The boost is going to 38 and at times 40 psi at higher rpm’s. I was just wondering with warmer temps does that play a factor with turbo bark????? It just feels like the motor has no low-end power till the turbo ramps up.

well well well
I did the intake gaskets and still no luck yet. I am down to the turbo, map, and injectors but witch one??? Now if this was someone else’s truck I would have fixed it by now but no not my own. They say it does happen that way if you’re a mechanic your car is the last one fixed like if you’re a painter your house is the last to get done and so on and so on.

I doubt its the injectors-I had one bad one and it felt like I had a hot cam at idle-very rough idle that disappeared over 1600 rpm. If your gauges are accurate I don't see how it could be the turbo as you say you are getting 38-40 psi of boost. I wonder if you are seeing the intermittant voltage spikes in the pcm. This is popping up alot on all autos and most people don't evan know it. If you are getting these spikes they rapidly lock and unlock the torque converter many times a second and makes the truck run slower. There are many factors to this and from what I know someone is coming out with a box that totally eliminates these spikes and improves performance even on stock trucks. 
turbo??
It still could be the turbo at low end or from a stop! If the turbo doesn't ram up as quick at low RPM as it did before then it could cause this. I know that the t/c is not locking up because I removed the pin out of the connector. Yes it could be the MAP sensor because if the MAP is not in range then it’s not going to fuel the motor like it should even with all the power box’s and injectors. I cleaned the map and still didn’t feel any change but I am going to replace it still. It has a new AIS sensor in it.

Given your's and my past history I should just stay out of this one but the TDR is for sharing information and i believe in honesty.
One way to check the map sensor would be to hook onto a trailer and do a performance test. This test is best done with a load, like a trailer.
Run through the gears for a mile and see what your time is.
Now run through the gears for a mile again only this time unhook the map sensor and see what your time is.
If the performance times are the same or real close than your map sensor is o. k. , if the times are way off then the map sensor is the culprit.
This test will set a code.
