No boost and drinks the fuel

[SPLtank]

Help.

This time last year my truck would reach 30lbs and smoke the street out.

Now I can barely get 6 and no smoke.

I have cleaned the tank shimmed and checked fuel pressure and even replaced the fuel pump.

Seems like lack of fuel but that side should be good to go.

Where do I go from here?

uppipes leaking? you have a huge boost leak.
all ic boots tight? no leaky boots?
have a pyro gauge? bet you have insane egt's.

Did up pipes and gaskets last year.

If it were a boost leak I would have tons and tons of smoke. Ive lost an intercooler pipe before and couldnt see the car behind me for smoke.

As of now I have NO smoke and no boost.

100 lift pump psi!!! thats tooooo high

200k on sticks is a lot wouldnt you think? i would do a cont test and buzz test if you can get a scan tool. maybe time for a rebuild. do you run good oil? change it often? and your oil level is good right?

you can geta icp on ebay for around $60-$70. but unplug yours and see if there is oil in the harness.

Im leaning toward the HPOP. I have gone through the fuel and urbo system.

ideas?

ok well test the hpop then.

get a scan too and look at icp psi.
go out on the highway and get up to 60mph. floor it to 80-90mph and tell me what readings you get. right of the bat it should spike and then level back down at a #. so for ex; mine spiked at i think 3250psi and then leveled out at 2750psi. thats good for a 15* now a good 17* should do at least that.
