hmmm, it sounds gutless as hell but everything sounds like it right.... when mine was stock years ago i could tow our gooseneck trailer and fork lift up the mountain no problem? and i'm around 7k in elevation.... try throwing a cold air, 4"turbo back exhaust, and a 6 position chip w/custom tunes on it, that should be plenty of power after that

Air and exhaust will definately help. Most vendors dealing with a 6-POS chip have a veriety of tow settings too, look into it if you go that route. I rarely tow anything but I had one put on...never know when the wife may say "F**k it, go buy the boat you want."

There is no point in throwing power at it if its not running right stock

thats kinda what i am thinking i dont want to put a bunch of performance to it and it cost big. everyone always said the 7.3 is a super strong powerful truck thats y i got it but mine but mine is a dog and i hope its some thing easy haha what what else could it be... 2002 F350 XLT 4x4 cold intake exhaust straight pipe NEW CPS IPR oil changed fuel filter changed ran injecter cleaner through it. Could it be the turbo impeller? wastegate? something eletronic

Need to get a scan on it. Find out what the ICP pressures are and duty cycles are when cruising down the road.

Also do a cylinder contribution test.

My Wifes EX, also on 37's and 3.73's... Intake, exhaust, chip and a 38r with a 1.15 housing...

No issues towing with 37's and stock gears...

truck has 35" tires (not a big difference)i bought the truck as is and am thinking about a 4:10 or a 4:30 but there still sould be a little more power there. If i unplug the waste gate vac line i make 25LBS of boost but when plugged in 19 max no more. Also on the ICP it is new it not stock the ICP in spliced in the the wiring y i dont know but it is aftermarket. i ask the guy i bought it from about the truck haing little supdder and he said just use some injecter cleaner and didnt do anything. by lookin at things the guy i bought it from addressed the problem (spuddering) but never fixed it. i fixed it by replacing the IPR VALVE
