Truck is running great. My boost readings come from the new AIH plug with the boost fitting. I tought maybe that had something to do with it cause before I had it in the map line with the T fitting.

AIH plug is where mine is. I cannot believe that your truck runs great with those up pipe to turbo housing leaks. There would have to be a loss of turbo boost potential there. The truck may run fine but does it make good power? Did it leak when the reference port was the map sensor T fitting and did you have good boost numbers then?

On your compression fitting at the aih is there a metal plug in the line the size of a pinhole? My original fitting had a small pinhole to limit how fast the air is measured. I took that out and put a normal fitting in and now I have a instant boost. I compare that with my electronic banks boost from the map sensor, and the reading is 4lbs different and will not respond quickly. The manual guage will go up to 26lb and the electric will not go over 24 and freaks out if its stays there. Just to compare. I dont get temps near 1250 unless Im doing something wrong. I used to have that temp all the time with an exh leak.

Truck is making good power but like I said I have almost no boost til I stomp it. By the time the boost shoots to 25 it's time to let off. I'm not sure if it was leaking before with the map fitting but I think it might have been. I started noticing smoke coming from the floorboard about a month or two ago. Boost PSI was about the same with the MAP but my old gauge would steadily climb to 25. No meaning slowly but smoothly. Now it's like the gauge gets stuck then just lets go.

Man Lance, I would say fix those up pipe leaks. I bet your truck will run 10x better and it should solve your gauge problem. That's my .02. Then look at what Kennedy said if no satisfaction. I think your exhaust leak is your problem.

Thanks for all the help. I gotta find those pipes tommorrow. I hate to think that I might be losing all that boost through a leak. I might try what kennedyford said to cause the hole in that AIH plug is pretty much microscopic. I don't guess it would hurt to change that fitting would it? I know the one on my gauge has a bigger hole in it.
