you guys are talking about two different trucks. the banks on an idi, which your 93 is, should make about 7-8 psi of boost under a load. 1-2 psi unloaded or at cruising highway speeds. also, unless someone added an intercooler, your 93 does not have one. i did not see one listed in your sig. the turbo should go right into the intake hat. the 7.3 in his 01 is a different motor. it was built for a turbo and should be putting out boost in the 20's. and they came intercooled from the factory. your egts look good, so your turbo is at least somewhat working. anyway, hook up to a trailer with some weight on it and find a hill. give her hell and see what the boost and egt gauges read.

if it is a k&n, it should all ready be pre oiled. the oil is dyed red so you know where it has been sprayed. if it is not oiled, the cotton, or what ever the material is, should be white/ gray. banks uses k&n filters for their system, but i had read there is not a k&n part number for it. so you would have to go through banks to get it. so.... maybe banks does not have it pre oiled. k&n filters have a recharge system, so you can clean and reuse the filter. it comes with a spray soap and spray oil. if you half to oil it, spray along each pleat lightly and wait 10-15 minutes for it all to soak in. then you can see where you missed. you do not want oil dripping off it but you want it to be a solid red. if anything, using a grease around the rubber edges will help seal the seal, if you get what i mean. it is a little extra insurance that nothing is getting around the rubber seal. i have been using k&n's for a while so if you have any questions, let me know.

to answer your other question about turbo whistle, it is mainly determined by you exhaust. a system w/o a muffler will let the turbo whistle a lot, i should not say let it whistle, you will hear the whistle a lot more. a performance muffler will let some whistle out. a normal quiet muffler will make it hard too hear the whistle. these motors were not made to be turbo'd, as in the compression ratio is really high compared to the newer diesels which were designed to have a turbo. the idi's have around 21.5:1 ratio, where the newer powerstrokes only have around 18.0:1. they rely heavily on boost to make power and can handle to 20+ pounds of boost. out idi motors can only handle up to around 12 pounds safely. after that, the head gaskets can not keep that much pressure contained. boost is made by fuel in our diesels. so the more you put your foot into it, the more boost is made. so just driving around town, you will not see high boost numbers. you will only see higher bosst number when you are really getting on it or hauling a load. clear as mud yet.

yep, that's the color of a preoiled, ready to go air filter. when you get a recharge kit, that is what color you want it to be when you re oil it. i would use grease around the rubber, i dont think oil would stay where it should to be effective. i dont think what kind of grease matters. but someone might have a different opinion.

arthur, do you have an egt probe. what are you running for egts loaded up a grade. you might have room to turn up the fuel a little more which would raise your boost numbers. did you turn it up the banks recommended 1/4 turn of the fuel screw.
