Thread: Mods for Towing a Caravan

My go to Mechanic thinks Auxiliary Auto transmission cooler and Chip to boost performance. Is the mileage on car an issue when considering boosting performance?
I would be very interested in people’s thoughts and ideas on this as I really have no idea.

Definitely a tune from td5inside and an egt gauge. If your going to be towing heavy loads then a transmission oil cooler is a must. And tow in sports mode. Also probably upgrade your exhaust manifold bolts. You don't want to warp the manifold. Make sure your radiator is in good nick. And a good set of intercooler hoses.

I also forgot to mention that mine has 350 000km on it now and it's still running great. The auto is showing signs of being a bit tired but still shifts good. Im running 23 psi, big intercooler, tune and hybrid turbo. Keep on top of maintenance and it will look after you

Also tow in 3rd locked up for hills and slower cruising, this will reduce heat generated by the Torque Converter.

My d2a at 260000 odd kms tows a cub drover supermatic ball weight of around 175kg
mine has 32inch tyres a 2inch lift fitted poly airbags suit 2inch lift to cover ball weight
I tow in 3rd and don't even know it's on the back the disco loves it
I watch the egt gauge at steep grades and adjust driving to suit Egts
I only ever sit on 90/100 kph and get around 16-17/100 fuel economy towing the camper

Excuse my ignorance but what is a typical EGT???

Sorry also no other Mods, cooler, performance remap, chip??

Exhaust gas temp (egt) mine sits on 500 degrees towing on flat then creeps up to 600 degrees up hills only other mods I have done removed egr a decat pipe other than that standard disco excluding duel batteries ect ect
Edit - actually drove today towing egt sitting on 400 and highest got was 500 at 36 degrees outside temp
