There are alot of after market products for diesel engines.eg computer chip, valves etc
Does anyone know what may be available to improve the fuel economy and towing performance of a petrol 4.8ltr patrol.
cheers Trevor.

What sort Trevor manual/auto year?
You can go from wild to mild.
One of ours generates 400kw and can take out our recently departed HSV Maloo mainly due to a 4" turbo system.
However my daily driver 2010 auto 4800 has had its towing performance improved simply by having the transmission reworked.
The manuals have an aftermarket computer option , Haltech , and this can be remapped with milder exhaust/breathing mods.
Unichips etc make little difference.
An aftermarket exhaust will make some difference but only at the cost of noise increase which is a compromize I am not prepared to do.
Nothing can make a real difference to fuel use though except keeping the standard tyres on as much as possible , i.e. not making the car worse with extra rotating mass and bullbars etc.
I can get down to 14lt/100km with careful driving and with petrol so cheap I don't worry to much but times will change I guess.
