How will towing a new 5th Wheel with 1994 7.3L IDI (non powerstroke) Turbo Diesel be?

Not sure I get the description of issue,, the bang is confusing,, I would check to be sure the fuel filter is not lose or the housing is not sucking air. Keep in mind that with your increased fuel used for the tune you are elevating your egt the turbo and the exhaust are likely getting excessive heat while towing. By the way this is not a good thing. I would install a egt sensor and keep a close eye on it.

My 4.7 liter V8 on my Jeep Commander pulls that just fine. However, I do have the separate cooling system for the transmission to keep the extra weight from overheating the trans. I also have a TOW button that re-gears the transmission lower. The BIG question is what is your vehicle rated to STOP. My Jeep has a full towing package and is rated for a heavy weight like this. It has HUGE rotors on the 4-wheel disk brakes.

I would not try it, get a friend with a bigger truck. the transmission and diff on the 4 cyl trucks are only designed for light duty like what u can fit in the box and not much more

con rod bolt tension is 55-60ft/lbs
crank shaft main bearings is 80-85 ft/lbs
fly wheel bolts95-100 ft/lbs
crank shaft pulley nut 94-123 ft/lb
head studs tension 80-95 ft/lbs working in a spiral direction from no 1 stud directly in the centre of the head. Pull down in 10ft/lb increment starting at 20 ft/lbs
valve clearance is .010" both valves cold but after warming engine and re-tensioning the head studs re set valves to .012 both valves
injector retaining nuts tension12-17 ft/lbs

as you can see you can tow us to 3000kg or 6600 lbs IF the trailer has its own brakes and 750 kg is it doesn't.

Uhaul will not rent you a trailer to haul anything close to what the maximum towing rate your vehicle is listed at.

which diesel eng does the truck have? If its the powerstroke it is located on the firewall, if it is the non-powerstroke(IDI) engine it does not have one as the fuel pump is mechanical.

look in the driver door it will tell you i pull a gooseneck with 30000 on it all the time with no prolbem my wieght is 30000

THE POWERSTROKE IS WHOLE DIFFERENT ENGINE THAN THE NON TURBO 7.3..

usually 1 of 2 things-lack of lubrication or a foreign object in the intake.at turbo speeds,the smallest object will wreak havoc.

It depends on if it is an automatic or manual, 2 wheel drive or 4 wheel drive, but I would say no more than 5,000 lbs. just to be on the safe side
