Ok guys, keep the idea coming but also help me with this:
Ok here is what happens. I was driving to work, I have to cross train tracks, which i cross at about 55mph kinda rough, about a second after i get across them, my truck bucks and the engine cuts out for a split second... strange. On my lunch break i take it for a spin to see if i can get it to do that again. I nail it off the line and it cuts out and misses bad. My fuel pressure gauge stayed strong at 58psi, so i doubt its a fuel pressure drop problem... No cel or anything during the miss. I get up in 3rd gear, with od off at 70mph, it kinda cuts out for a second then picks up, i ease into the gas and it doesnt miss at all. I try it again from 70, and it misses. Ok, so seems like only under heavy load it will miss. I put it in 2nd at about 50, nail it, and it pulls strong as ever, no miss at all, so i assumed the problem must have fixed its self, i stop on the road, and take off hard, not WOT, and it cuts out and misses bad again... If I stay under 10psi in first gear it wont cut out, in 2nd gear I can go wot and no miss....

Curios if you could use that to rule out a fuel problem.

it reads 38psi at idle/cruise, wot is 58psi, and it just goes up as the boost goes up. its very sensitive. the second i hit the gas it goes up, and the second i let off it falls fast to 38
