so i got my lift pump workin now but my truck is still super slow and i just cant figure out whats wrong its startin to make me mad. i can have the edge on 5 with my foot mashed and i have about 13-14 fuel pressure and i cant even hit 950 degrees on my egt gauge and the truck at highway speeds doesnt smoke much. my buddy has same set up with 125hp jammers and he smokes me and he can make things dissapear on the freeway with smoke i just get a little haze. Any ideas on whats goin on im so confused.

 

How long was your BD lift pump dead? might have hurt the pump

 

well i never reallly ran the truck when the pump was bad but i did a little so do you think maybe its the injection pump?

 

Well it could be your map sensor. Un plug it and see what it feels like if no change change it out and plug a new one it.

 

U might try pullin the IAT sensor and cleaning it while your there messing with the MAP.

 

Try replacing the map (boost) sensor. It's a $100 dealership part but I've put 3 in since I installed my edge. You can't clean it either. If your edge reads no boost it won't add fuel.

 

thats funny when I use the edge comp and unplug the map sensor out of the head but leave the edge hooked to the factory map connector my truck fuels like a champ almost over fuels on the bottom end. How much boost are you building? what are your setting set at on the edge for egt, boost rpm etc. It may just be backing down.

 

Correct me if im wrong guys, but my understanding is that the Edge already has a boost fooler, correct? and it says in his sig he has the Edge and a boost fooler. could that possibly be a problem?

 

ive got all the back downs set good and i see 38-40 psi of boost on a good day

 

you should be making good power at that boost. Maybe you just have a vp that doesn't fuel very well.
