I have recently bought a new caravan which is 2 tonnes and the petrol engine performance is poor due to the high gearing and not so great torque low down. The previous 120 I hadcwas much better. Is there a chip available to improve towing performance

I made enquiries about a chip for the 150 petrol, and was told there are none available, and was also told the engine is very efficient and does not need chipping anyway.Originally posted by stowe View Post
Like you, I tow a 2 tonne van, and the hills can reduce speed a bit. I use the auto shifter like a manual changer, and sometimes lock in 3rd driving up the bigger hills. I don't drive in 5th or 'Drive' when towing the van, unless driving on a slight downcline where there will not be much stress on the transmission and engine.
I am looking at a different exhaust system with a straight flow muffler, which may improve performance slightly.
The only other option is a turbo or supercharger addition, rather costly though.

Hi Stowe
Maybe look at lower diff gears. There is a place in the usa that sells kits and there on Ebay. I put lower diff gears in my holden crewman and its the best thing i have done to the car. Maybe look at changing the value body in your auto to change how it shifts. Talk to a good auto guy about that or the Auto wherehouse. Also look at your exhaust and headers.
Cheers

Mate, when I bought my camper I decided it was time to go from Petrol to diesel for torque reason and fuel economy. Hard to go the other way.
