Hey Bradford welcome to the forum. What year is your truck?

01 lariat ext cab short bed

I'm not sure what the deal is there. Maybe a guage malfunction. Does it seem to pull a lot harder once the boost jumps up to near 30?

does'nt seem to pull any harder when it comes up but the ses comes on, (line off accuator) all seems to work fine when returned to stock and line reconnected , possible programmer problem ????? truck used to go good , smoke with progammer .But returned to dealer with a idle & surge problem a month after programmer install (ford warranty) when i got it back did'nt go as good and no more smoke. Any idea's

[99Smokin73Stroker]

That's wierd...maybe the dealer messed something up or didn't put something back together properly, cuz i'm not sure!

how much boost should i get off idle

[99Smokin73Stroker]

Not much if it's idling. My buddy's cummins idles a little less than a pound of boost. It's a digital guage and it flashes back forth from 0-1lb.

sorry i was not clear , i mean mash the pedal from a stop . should it make any boost ?? if so how much ???? I'am used to marine diesel's which start making boost just about off idle ,but its apples to oranges (marine-truck)

Do you know if the dealer reflashed your ECM? If there is a different software version that could change things up a bit maybe.
