Well, I finally got my fuel pressure gauge installed. Turfed the isolator (what a nightmare, trying to make THAT work) and am running fuel right to the gauge with a shut off valve right at the vp44. After bleeding the system (and pouring about a cup of winter diesel right into the drivers seat, not to worry the fabric and foam sucked it right up) I have some numbers and am not sure if I should be concerned. At idle I get 14 psi, cruising on the highway I get 10 and WOT I'm about 5.5-6. Is this normal? Also, my egts are only about 850-900 pre turbo at WOT, not towing anything and the rear end sliding around on the highway (it was only -22 here last night and black ice) FUN!!!.
Thanks.

ya that is pretty close to how all the stock ones i have seen are....make sure it doesnt go below 5, thats the "unsafe" number from what i have heard....be thinking about a differnt fuel system, because that stock one probably wont last long..

completely stock that sounds right.

sounds about right. once the weather warms up, your pressure will probably be slightly higher. I think the coldest its been here is 25*F and even with my FASS system, I've seen my fuel pressure drop from 21psi at idle in the summer time, to 14-15psi at idle. And thats with PowerService's anti-gell additive. Once warmed up, it comes up to about 16-17 at all times.
