Default surging under hard load

Well I was at the dyno this weekend and put down some ok numbers but I have been having a surging issue when I have my edge on 6/5, like im running out of fuel, or I have a timing issue, it runs smooth when I run the edge on 3/5. What I have is in my sig. Just wanted to know if anyone has had these issues with the edge or with jammers?

i have the same prob! but the sending unit for my fuel press is not working. I had it manualy checked. The guy that checked it for me said i was good but he only let me take my truck up to 2000 rpms. Im going to have to find a sending unit. Mine runs fine untill i run it hard on the higher settings??

Has anyone had this problem with jammers or the edge? it started when I installed my new used turbo. I could only get 32lbs of boost on the rollers

My truck does this from time to time. It did it worse with the Adrenaline than it does with the Edge. I believe ive narrowed mine down to my 128K mile VP44.
