you may seen my other post but i have stage five edge jammers and supperchip it runs fine without the superchip if you run both then it cuts out at w.o.t. it smokes like a freight train with the supperchip at first till w.o.t.then the smoke cleans up and if you keep going it will run the injection pump out of fuel fuel pressure is good though and i have tried boost fooler fuel pressure is no less then10 psi at wot and 15psi at idle do i need more fuel to the injection pump thank you for any help

 

What is your boost? Should see the 30's! If your smoking you got plenty of fuel! Maybe not enough air. Yes the vp pump could cause this.

 

pull the codes and then report back

 

My superchip didn't do any prevent my truck from defueling at high boost operation (above 24psi). You might have to buy a boost fouler. I also found that the superchip smoked the most of any program/box that I've tried. If I was you I would pick-up a new or used edge ez. It should be fairly cheap. How much fuel pressure you running at wot? Your lift pump should be able to produce more than 8psi, if not you should think about replacing it.
