95 psd turbo woes

hey guys i have a 95 f-250 and just installed boost and pyro guages in my truck and found that i'm not making nearly as much boost as i thinnk I should.
i'm only makin a max of about 13 lbs boost and that is over 3000 rpm under full load, i make under 5 lbs untill i break 2000 rpm. this just doesn't seem right. The truck has about 130,000 miles on it and has a superchip programmer, afe stage 2 intake and the exhaust done from the turbo back.
i figure i probaby need a new turbo, any suggestions on brands and models, if i need a new one i may as well upgrade right?
thanks for any help.
Sam

Don't buy a new Turbo yet!! Something like that could be simple! There could always be a problem with the gauge or in the hook up, a small leak would bleed off alot of boost pressure going to the gauge. Better wait for some more input from the early PSD guys

does it feel like it's lost any power? reason being, if you took any of the intake componets off then you probably have a leak. tighten all the clamps up real good but not insanely tight. and get back to us and let us know whats up.

i have already checked for leaks at the guage and at the connection, and it doesn't seem to have lost any power since I installed the guages.
I was pretty disappointed in my power after the chip and exhaust upgrades, and the lack of boost (weak turbo?) could be why they didn't seem to help that much. the intake seemed to help alot tho, more than the exhaust and chip combined. thanks for the suggestions tho.

what's the compressor wheel look like? if it's toast then that's what i'd say is wrong. it should look SIMILAR to this one. but it may be made diffrent. thing's to look for are the vanes. CAREFULY feel them they maybe sharp. thats what it should feel like. if there dull like a butter knife thats bad.

Turbo

Hey I have a 1995 crew cab powerstroke dually %spd with 140,000. The truck runs absolutly great. Now. I added a K and N intake and 5" down pipe back. I installed boost and water temp gauges. ( i have the pyro but it has been cold and I didnt want to lay on the ground I dont have a cement floor shop.) I noticed when i installed the boost gauge in the little y pipe intake I was making 16 PSI boost. I drove the truck about 3000 miles and suddenly I lost 6 PSI. I can only make 10 on a good day and 16 was a common occurance. The turbo sounds the same and all it makes no funny noises and nothing is different otherwise. All clamps are tight and line hase no leaks. Now the intake side of the turbo fins look chipped up. I dont honestly know if the truck has been like this since I got it at 129,000 or if the air filter got some dirt arond it. Would 10,000 miles mess up a turbo sucking a very very very minute amount of dust? It is not dusty around here. thanks for any help.

yes....any dirt through a turbo can cause damage. the particles dont have to be very big, microscopic ones are the most dangerous because there is no signs of them till the damage is done.....if thats your problem, i dont know....but damaged vains do indicate likelyhood for a turbo problem......Marc

There's no wastegate on the 94.5-97's, but 16 PSI should be about right if you're not running a chip. You making only 10 indeed sounds like you dusted the turbo, and the vanes looking chipped up confirms. You have a pretty wide range of options for replacements, from having your stocker rebuilt to buying a modded one. After you get it all back together I'd look long and hard at that K&N, figure out exactly how dust got through. You might consider switching to a paper filter.

As a side note, my 96 as descibed in my sig will push about 23 PSI with the Edge set on extreme.
