    I have been working on the 95-97 generation 7.3L for a long time, and I know my way around the motor pretty good, but my 95 is not spooling up like it should be. I am not looking to go on a wild goose chase changing parts and wasting money, so if you know of a problem you or a buddy had with the exhaust/turbo on this truck please help me out.

    I have 2 thoughts of what it could be right now:

    1. Blown turbo- truck is not blowing any black smoke though, which is usually a give away the turbo is bad.

    2. Up pipes or up pipe gaskets.

    Any thoughts?

    Like I said before, I do not want to start throwing parts at the thing, I want to diagnose the problem and fix the issues. Thank you for your help everyone.

    it sounds like your up pipes are loose and leaking.

    it may be your warm up flapper on the turbo is sticking. sometimes in cold weather mine sticks and the trucks a total pig until i drive a few miles then it seems to work.

    I agree with Sno Commander, I have seen a few trucks with that issue. Actually bought a 96 reg cab dually for a sweet price because he thought the motor was messed up, it was just a stuck warmup valve.

    You can remove the butterfly but in cold climates it extends warmup time. Go over to thedieselstop.com and do a search; lots of info about this and anything else you may need to know.

    there is a plug with two wires under the turbo, unplug that...it controlls the ebpv (exhaust back pressure valve) but you will notice right away with a noisy hiss that sounds like 100 ball bearings in a coffee can

    for not spooling up... most likely the up pipes, get under the truck, look for the connector from the manifold to the upipes and you will see soot, if no soot then look for silicone boots with holes on the top of the engine. a clean air filter helps amazingly and then the fuel filter are pretty basic things to give the truck more pep.
